During the casting session before the club meetings, I have been using my teaching rod. Many casters have commented on the rod´s handle, and all have liked the tactile feel of it.
So, let’s face it we aren´t getting any younger. I broke my underarm in the eighties and it had to be operated to avoid it looking like Picasso’s goat. Resultant I have paresthesia in my right thumb. Then there was the Dupuytren’s contracture and then the arthritis of the base joint of my thumb (carpometacarpal 1) led to parting ways with my right trapezium bone. This is to be expected and I bet a lot of the club’s members have some of those ailments and some others too. With arthritis in our hands, it becomes more difficult to close the fist. I find it hard to get a good grip on the cork of a fly rod now.
What works very well for me is to make the handle thicker. I can get a much better grip on my rod if I do that. I have found that by wrapping my rods with bike handlebar tape I get a firm grip and it is not slippery at all. The wrap is soft and pleasant to hold, and my hand does not slip.
Of course, you can go and buy fly rod tape but any product with “fly” in it will be priced much higher than the bike handlebar tape. Try it out – it is cheap, and you might like it.
Most lines are designed so, that when you add a correct leader and a fly, the outfit will turn over beautifully and we are happy. In other words, the fly lines are designed to turn over a certain mass i.e., the mass of the leader and the corresponding fly. As I have repeatedly mentioned in these technical blogs, a fly line without the leader will kick when cast. All fly lines are designed to have a leader added to the end of the fly line.
Design of fly lines
A fly line is designed to work with a certain mass that you add with your leader and your fly. If no mass is added to a fly line – it will kick when cast. Correct leader and fly (correct mass) added can be cast as intended. If we add a lot more mass for instance with a heavy fly the casting becomes problematic again. So, all lines have an optimal mass that needs to be added for that line to work well. Of course, this optimal mass is always caster dependent.
(In the two-handed world, the lines are designed the same way, but the exception is the Skagit line where you always must add a tip plus a leader for the system to work. That is outside the scope of this piece.)
Lots of tips available
All the line makers produce tips that you can add to a line if you wish to do so. There are a plethora of various density and length tips available. They are marketed as Vesileaders – Polyleaders – etc. An add-on tip is a tip made of PVC or polyurethane meant to be added to the end of a fly line. Those tips can either be tapering or level. However, the mass of the tip is usually not to be found on the packing.
Why use them?
You can of course add those tips to fly your lines. But what is the rationale for doing so?
You are fishing with a floater and your friend who is using a sink tip is catching them right and left but you are not. You can add an intermediate or a sink tip to your floating line to get the fly down.
However, adding tips to floating lines not designed to take that mass is just a quick, simple way to turn a floating line into a sinking tip line, but at a price. These tips will weigh several times more than a conventional leader (16lb leader I have weighs 11.2 grain). The weight of the tips is not disclosed but rest assured it is much more than the leaders. That mass of the tip will have to be added plus a little bit of tippet and the fly. They will cast terribly, predictably. When you look up these tips you will find marketing blurbs – “Casts well and turns your floating line into a sink tip” – those are written by some good casters, and they can undoubtedly deal with the extra mass, but average casters will suffer.
The mass again
Since the drawback to tips is their extra mass, the relationship of the added tip mass to the line’s head mass is the important one. Therefore, of course, adding a relatively light tip to a heavy line works much better than adding any tip to a light line.
Any line can be made to cast these tips if the angler shortens their fly lines front taper. Thus, more mass is at the tip and allows a line to cast a heavier tip. When the mass of the tip of the fly line matches the mass of the butt of the leader all is well. In many cases, though that will mean sacrificing the entire front taper, to get a reasonable match between the fly line’s end and the tip.
From the floating line, we can graduate to sinking lines. The advantage of fishing a sinking line is obvious. A sinking line differs from a floating line in two important aspects. The line’s submerged part can’t be mended. The sunken line can’t be recast until it has been stripped or roll cast to the surface. The line needs to be brought to the surface for a pickup. Either the line must be stripped to the leader and/or roll cast and thus get it to the surface (digging the line up to the surface – we call it). For that reason, full sinking lines are not very practical in rivers as there is no mending and lend themselves better to lake fishing and saltwater fishing.
The sinking lines are called full sinking if all parts of the line are denser than water. The lines that have a sinking part and a floating part are called sink-tip/head (depending on the sink length) lines.
A. Full Sinking Lines
The full – refers to the fact that these lines have higher density throughout their length than water. They simply sink because they are denser than water, if and when they break the surface tension. That does not mean that the density will be the same throughout. Remember, the running line for instance is much thinner. The multifilament woven core contributes more to the overall density of that part of the line (practical density less), as compared to the head part (practical density more). This fact will affect how they sink and – fish. Badly constructed sinking lines can be unpleasant to cast but can sink and fish very well. Their construction revolves around how they cast and how they sink. The current sinking lines can be nice to cast if the density differences of the various portions are minimal, therefore they don’t noticeably kick.
I.P.S. this or that? There is no industry standardization behind the inches per second numbers. Each manufacturer has its own way. But generally, the inches per second (I.P.S.) we see printed on the fly line boxes is found by placing a piece of the fly line in a water column, and then the sink rate is just measured. The sink number given will be representative of the densest part of that fly line. I stress that this is measured in still water. Whether that line will sink like that, in the fast or slow water of a river, is another question entirely. You can safely rely on that the line will not sink as fast and not as deep in moving water.
Lines 1, 2, and 3 are co-called standard lines.
1. Intermediate lines
They sink, albeit very slowly, and therefore belong to the sinking line class. Why they are called intermediate – instead of slow sinking lines, I don’t know. Who says it must be logical? The density differences throughout the line’s length are modest; therefore, they don’t noticeably kick when they are cast. They are generally pleasant to cast and behave similarly to a floating line.
The slowest sinking lines are called intermediate and are supposed to sink 1-2 I.P.S. (inches per second). They sink slowly but sink very slowly if at all when stripped in. They are great when the angler chooses to fish just under the surface. The intermediate line can be used just about anywhere. I use intermediate lines in the salt, rivers, and lakes. The only drawback to their use is if/when the running line sinks making it a tedious process to “dig” up the line and recast. The coating of the whole line is of the same density. The running line is so thin that the density when we account for the core is less than the head’s density. Thence the running line will not sink much.
2. Medium sinking
These lines will sink 3-5 inches per second.
3. Fast sinking
These lines will sink 5-7 inches per second
Medium and fast sinking lines are built like the picture below indicates. The line’s density and therefore its sink rate varies between different lines. However, the coating is the same along the line’s whole length. The resultant functional density along that line will NOT be the same though because of the varying thickness of the coating and the contribution of the level core.
Because of the variable density along the line’s length, the belly of the line will sink fastest (it is the densest). The tip of the line is thinner (less dense), and it will sink slower. The RL will sink slower than the belly and the tip too. Therefore, the line will be in a U shape and strike detection becomes difficult because of the slack. Fishing a sunk line is all feel, and it is a serious handicap that the line isn’t straight. That takes us to the next type of line, and if you took your minerals and vitamins this morning you have already figured this one out.
4. Density compensated sinking lines
Above we have two different lines in this class. We can place the densest coating in the head of the line, and then a bit less dense coating in the handling part, and finally the least dense coating in the running line. When that’s done, we have three different densities along the line. Now, this type of line will sink straighter and does not become U shaped in the water (no slack). This will increase our hookups because of the elimination of slack and much better detection of strikes.
B. Sinking tip/head lines
The sinking lines above have one cherished quality namely they get the fly down, but mending is not possible, and you must spend time “digging them up.” So, it is logical to make lines that both sink and float. Mixing the sinking tip with a floating part. Now we have a line that sinks in front but can be mended and roll cast with relative ease.
1. Sink tip
The length of the sinking part can be varied and so can the density of the coating. These lines excel in river fishing. The fly is in the water column where the fishes are. You retain the ability to mend and control the line with the floating portion. A couple of strips will bring the sunken portion of the line to the surface from which they can be roll cast with ease. Your choice of density for the sinking tip depends on the size and flow rate of the river to be fished. Short slow sinking portion for a small river and a longer faster sinking tip/head for a big fast river. The length of the tip can be anywhere from very short say three feet to include the whole head.
This line has fifteen feet of a clear intermediate section (Belly 1), but the rest of the line is floating. Now, just the 15′ distal feet will sink, and the rest floats so it is very easy to recast. No roll casts are needed to bring the line to the surface. It’s already there. An additional advantage is the ability to mend if there is sufficient mass in the tiptop (see a previous blog). This line above is not great to roll cast because of its short head, but you get the picture. Of course, the terminal intermediate part can be longer or shorter there are many options to choose from.
This one is available in three density iterations, intermediate – sink 3 – and sink 6. The Sink tip is between 8-16 feet, depending on the line’s weight. This line’s head is longer making it easier to mend.
2. Sink head
This type of line has a head that sinks. It can do so slowly (Sonar Sink 30 Clear) to fast (Sonar Surf) it all depends on the intended use of the line.
This line has a clear 30′ head that is intermediate or slow sinking. The rest of the line is floating. There are two advantages to that. First, you can easily mend the handling part of the line, and second, you don’t need to dig the line up to the surface before recasting.
This line has a sink 6 (6 ips).
Casting sinking lines
Generally, sinking lines are more difficult to cast than floating lines. That’s not a big surprise now when we know how the lines are constructed with different densities along their length. They are heavy up front and can kick like a mule (….and bite like a crocodile J. Cash).
Usually beginning casters make two errors when they cast sinking lines. One error relates to the cast. Understandably, they try to cast the sinking line as they would cast a floating line, and that does not work very well. The other error relates to the leader. The butt of the leader anglers use is very often way too thin, so the transfer of energy will not be optimal. https://everyjonahhasawhale.com/blog/your-butt-is-too-small/
Am I serious? Now doing a piece on the running line – really? You might think that the running line is the simplest part of the line system and it might be. That there is nothing worthy there of any thought or writing. You would be wrong. Let’s dive into it.
What is the running line?
The Running line (RL); extends from the line’s end to the beginning of the rear taper (RT) into which it seamlessly blends. Below is the Amplitude Anadro with its forty feet of RL.
Why do we need any running line at all?
The mass of the Anadro is mainly in the head of the line. That’s the part we bend the rod with and subsequently, as we release the head it pulls the RL out. Let’s cast with and without an RL and examine the consequences. We cut the RL off and tie the backing straight to the Anadro’s head. The head will shoot out just fine, but it will become very unpleasant to strip the line back with the backing. For this, to work, we need to have some backing off the reel. Nothing tangles as bad as thin backing and we will run into that problem with the loose backing. This line lends itself well to very long casts, far longer than the head’s length (60’). Therefore, it is much better to have those 40’ in the form of the running line. Better for handling and it does not tangle as grievously as the backing. The running line is thin, self-lubricating, and textured (see the previous blog) and has a low coefficient of friction.
Even with casts up to 100’ we have good control over the cast and gain control over mends as soon as we have stripped to the RT. By choosing a line with a long rear taper we can compromise, and still have enough mass in the rod tip to have very good control over our line for our mending. And we still have excellent casting control over the line.
Let’s look at another line, the MPX. The MPX’s head is only 36’ (6# line). You can get this line out faster since the head is considerably shorter than the Anadro’s. It will turn over well because its mass is pushed forward in the head. The FT (front taper) is now 5’ and you can still turn over a fly gently. If you cast it far you will much prefer stripping in the RL instead of messing with the backing. The head is 36’ plus for instance a 9’ leader, and you should be able to comfortably roll cast all those combined 45’. Most casters can’t roll cast more than 50’ and seldom need more. The Anadro can be roll cast further because its head is 60’. The reason behind this is down to mass again. The running line is simply too light to move the much heavier heads.
Do you believe me now? We do need a running line. A very thin one will cast the longest but is prone to tangles. Too thin a running line is just plain unpleasant to touch, and is difficult to handle, and is nothing but trouble. The thin line has less friction but tends to tangle but by making it stiff we can counter that to a degree.
Stiff lines are coily but we can pull the coils out by stretching the lines, but we always seem to forget to do that. The RL tangles less if it is slick. The slicker the better. Both these lines are self-lubricating and textured but by applying silicone or such they can be made slicker decreasing their tendency to tangle.
A very thick RL is heavier and has more friction. So, the solution is the compromise in the construction of the rear taper. We don’t have much choice in the diameters of the running lines we buy, but that’s fine, the manufacturers have honed it to the best compromise size for that line weight.
Imagine that you are swinging a fly with each of these lines, and you have 55’ out, and you need to mend the line. In the Anadro case, it is easily accomplished because there is enough mass in the tiptop to move the rest. However, in the MPX case, you will find that much harder as you only have the thin RL in the tiptop and not enough mass to move the rest of the fly line.
Casting with overhang (length of RL outside the tiptop) is not easy for most casters. Just by glancing at the picture of the lines above it is clear that the Anadro lends itself to longer casts. When carrying 70’ of the line the overhang is 10’ but is 38’ with the MPX. So, the ratio of the RL to head length is a really important parameter. Those who can cast with overhang do it by keeping the running line and the head straight. If that’s accomplished a thin light line can power a thick heavier one. However, when the RL isn’t straight the cast fails.
The variables of the running line
The diameter is important. Thin lines shoot much better than thick ones. They are lighter and have much less friction. But a light coily running line can pose several problems. It gets blown around especially in a boat and that leads to tangles. Coily lines manage to tangle all the time. Of course, by stretching the line the coils can be pulled out, but anglers are mostly a lazy bunch. Thicker running line affords better control of the cast and the mending. However, you can’t cast as far because of their weight and friction.
The mass is important. Small diameter leads to a light running line (see above). Additionally, a light running line in the tiptop can’t control the rest of the line. The mass is simply too little. By increasing the diameter of the running line we are also increasing its mass. That gives us more control over our casting and line mending. But it also leads to shorter casts (see above). If the line was a conventional full sinking line the RL would be made of the same high-density material as the head. Might be small but would still be heavy, but he mending considerations don’t apply to the sinking lines.
The stiffness. Thin stiff running lines shoot exceptionally well. But a thin running line tangles so easily, but being stiff is a sort of an antidote if the line is stretched straight.
The COF (coefficient of friction/slickness). We all know that the hyper slick thin, light, running line is going to cast farthest of these combinations. All other parameters the same – the slicker running line is going to shoot the best. We even have textured self-lubricating shooting lines now.
The density. Mostly the running lines are floating parts connecting to a whole head, that can be floating, intermediate, or with varying sink rates. The RL and the head of the line (RT + belly + front taper (FT)) come in one piece, sometimes called an integrated line. Thus the “running line” is an integral part of a WF line. Most integrated lines (which are WFs) have a small diameter, light RLs but very heavy heads.
Mostly the RLs will have the same density along its lengths. There are conventional full sinking lines made with the same material its whole length.
However, there are modern lines where the RL comes in three densities. The Sonar Titan (Hover / sink 2 / sink 4) has a hovering RL for approximately 45’ and then there is an approximately 20’ part with sink 2. The head is finally rated sink 4. (Sink 2 simply means that it sinks approximately 2 inches per second (ips), etc.)
Then there is the Sonar Titan (Sink 3 / sink 5 / sink 7). This one has a sink 3 RL for approximately 45’ and then there is an approximately 20’ part with sink 5. The line terminates in the head with a sink 7.
So, we can have lines where the RL’s density is the same throughout, but these two examples are sporting two different densities in their RLs. These lines go by the moniker – density compensated lines.
I hope that you now agree with me that the running line is a very important part of the fly line. I would certainly sorely miss my running line if it were not there, next time I go fishing. And now you too, have an inkling how it works.
“What fly line do I need?” – is a much better question.
This a recurrent question we all get personally, or it appears on some chat site. There is really no correct answer to this question. However, the chat sites immediately fill with – “I just got line x, and it is wonderful, can’t go wrong with that.” And more in that vein, lots more. The answers and advice are all given in the spirit of generosity and are undoubtedly well-meant. But this question can’t/shouldn’t be answered, until you have an idea about the intended use of said fly line.
Choose a line for the fish species?
Ok, so now you think the choice of line revolves around the fish pursued. That would be wrong, too.
The mass of the fly to use dictates the line choice!
There it is – once again and we come back to mass. But think about it a bit. How can it be any otherwise? Mass moves mass, and therefore the line’s mass must match the flies mass. The correct way to go about this, is to visualize the flies to be cast. Not their colors or shape, but their mass (and drag, too).
Let’s assume that the prospective buyer is a novice to trout fishing, and she/he loves casting weighted Wooly Buggers and Streamers. However, on the advice of well meaning anglers (or pranksters) an Amplitude Trout is purchased. The reason I use SA’s lines is that they are the industry’s leaders, and their lines are the best I can get for my needs.
This line is absolutely fantastic, but not for Streamers. Why not? The forward taper is 12-foot long, and hence there isn’t enough power in that head to turn over a heavy Streamer. So, now we have recommended a fantastic line for smaller flies, but the angler wants to cast big and heavy. That’s not a good situation to be in if the advice is heeded. Pay attention the the Trout’s long rear taper. This line can easily be cast far. So, what is a good line for an angler casting streamers. My advice would be the Amplitude Anadro line.
The Anadro has a short front taper (2-3′), and that means it will turn over hard, and it has the power to carry a heavy Streamer. On top of that, the Anadro is 1.5 sizes overweighted, meaning that a #7 Anadro weighs between a #8 and a #9 line. That will ensure plenty of power to turn over heavy flies. The Anadro excels at long distance casting and that is evident by looking at the long back taper. The reason that lines are not true to their line designation is that rods have become so stiff that only elite casters can bend/load them with the designated line. Intermediate casters must have more mass (line size up) to bend the rod. The line makers know this and have responded accordingly.
The second question I ask is how far can you cast or how far do you need to cast? Let’s now imagine that our angler is casting light flies in a small stream. The Amplitude Trout would easily work for that job. Of course, there are other lines that could work, too. For instance, Amplitude MPX or Amplitude Double Taper. What about light flies in a big river? The Amplitude Trout would be perfect in that situation because of the long back taper making long casts a breeze. Heavy Streamers on heavy lines banged down are probably not a good idea in a small stream. But they are absolutely an excellent idea in big rivers. Pay attention to the Anadro’s long rear taper of 30′. To be able to make long casts, this is the best taper configuration to accomplish that.
Bonefish are notoriously wary customers. Something big and heavy landing on top of them guarantees that they bolt, and fast. So, we use a line that we can lay down gently. Because of the usual wind on the salt flats we need rods #7-9 to be in the game. The flies we use could easily be cast with something smaller, for instance #4, but the wind would kill us. This is a good example of the necessity of using tackle to cast a light fly. This is frequently done too, when casting small flies to big salmon. When I have gone fishing for bonefish, I make a beeline for my Amplitude Bonefish lines.
Generally, when fishing in the salt you are use something big and heavy. Therefore, you need a line with some serious punch. Or in other words, a line with a very short front taper. The Amplitude Infinity Saltwater is a good all round choice.
If you still need more power to turn over some monstrous fly, there is the Amplitude Tropical Titan. Here, a lot of the head’s mass is pushed forward, and this baby will turn over hard.
First choose the fly – then the line
Now, the process of choosing the tackle is obviously going to start with the fly. First you must have an idea of the weight/mass of your intended flies to be cast. Ok, so now when we have that clear, we can choose the line that has the physical parameters to be able to cast the chosen flies. Remember, heavy lines can cast both light and heavy flies, whereas light lines can cast light flies, but struggle or can’t deliver heavy ones. There are only two parameters of the fly that influence its castability. Firstly, there is its mass, and secondly, the air resistance or drag.
Now lastly the rod is chosen
Now when you have chosen the line size that can handle the job, it is easy to pick a rod that can handle that line. Now remember the marketing in our sport is pervasive. Anglers have been led to believe that they need a trout rod, then a salmon rod, and my God don’t forget the saltwater rod. This is utter nonsense. The rod is a piece of graphite, handle and rod guides. It bends, then straightens and can easily break. It is dumb as a brick and an inanimate object. I use my #8 NRX Loomis to cast certain weight flies, and I happily use that rod for all fish likely to take those flies. A heavy line and heavy rod, can deal with a heavy fly, and also a light fly. The converse does not work. So, don’t show up under gunned.
It is important to know that there is no objective parameter to adhere to when a rod is made. After a rod is made, it is cast by some expert with various line weights, and then the expert decrees, “this is henceforth a #7 rod.” I repeat, no standardized objective measure decides the rod ratings. This newly minted #7 rod obviously casts best with a seven line, if you are the expert. It might work best for you with an “8 line, and some would like better to cast it with a #6 line. All fly rods can cast several line ratings, there is nothing mysterious about that, and it is perfectly fine to use the line weight you like. So, all this writing about the crime of underlining or over-lining is a bit misleading. It is your rod and your line, and just use it as you like best. You have my blessing.

The running line is called celestial blue. The belly part is bamboo colored, and finally the front taper is blue heron. My eyes say grey, but I can go with blue heron too, because it is grey. Initially, I did not like these Harlequin lines, but now I love them. I find it advantageous to know how much line I am carrying, and with the coloring scheme, it is so easy. These colors also help, when I am teaching casters. Many of them tend to slip out line as they are false casting, and thus exceed their carry limit (all casters have a limit as to how much they can carry of line (keep in the air)). Most intermediate casters can carry 40′, and I use the end of the belly to remind them of the position. Casting with too much overhang (running line outside the tip top) is hard for beginners, but if they practice, they can carry more and more line, because they can keep the backcast straight. The front taper or grey part is about 12′ and the leader is 9′. Being cognizant of these lengths helps to pinpoint where the tackle is.
The core is braided multifilament nylon. The filaments are solid Nylon, but braided together to make strands (16 strands). The way they are braided yields a hollow braid. Each strand of yarn has a small amount of air trapped in it when coated, but most of the air in the core is in the hollow center, see previous blog. The line is not painted after being made. The PVC used to coat the core has a blue – then bamboo colored – then grey pigment, and the micro-balloons, added into the PVC coating mix. This coating transitions from one color into the other seamlessly. How that is done, I haven’t a clue, so we all can be glad that I am not the one doing that. The SG of the PVC coating of the level tip is nowadays 0.85. On top of all that the gray part has more air trapped in the mix (see later).
The line has seven red boxes with some hieroglyphs on the website. I will decipher them as we go. On the website there is some text under each box, but much too small for reading. Probably put there by the elves making these lines.
Two types of texture
1. The Shooting Texture
After the coating is applied it is time to texture/emboss the line. The running line is textured/embossed with what SA calls, “Shooting Texture.” Textured lines have less contact with the rod guides, so they shoot better for more distance when needed. The texturing also increases the surface area of the line for better floatability. This texture is not rough on the fingers, but the rear taper is not textured to give a tactile reference point (see later). Then the Belly of the line is textured with the same “Shooting Texture” to the front taper. Shooting texture helps, you guessed it, in shooting the line, and it increases the floatability a little bit, too.
2. The Floating Texture
After the coating is applied it is time to texture/emboss the line. The front taper and the level terminal tip are textured with the so-called “Floating Texture,” and that is an ingenious engineering application of the so-called “Lotus effect.” – https://en.wikipedia.org/wiki/Lotus_effect – Now, an engineer at SA applied this knowledge to the surface of a fly line called Sharkskin in 2007. The natural hydrophobicity of PVC was kicked up several notches, and the line floated higher. Although the Sharkskin line shot great and floated high, the surface is rough on the fingers, so now the texture is limited to the front taper, and terminal level tip, and it increases that part’s floatation. This part of the line is not handled much.
I will repeat this. The line is textured/embossed with two different types of etchings. Seriously, this a job for dwarves. “Floating texture” helps, you guessed it, in floating the line, but its cast-ability is immaterial as this part is almost always outside the tip-top.
Improved dry tip
The crucial part of any floating line is the floatability of the tip. By increasing the amount of trapped air in the tip section (the gray part), the SG can be brought down to 0.80. This will float the tip higher. The tip floats because of manipulations of the SG, and by manipulating the surface into becoming hyper-hydrophobic. This is really hard core engineering.
The AST (Advanced Shooting Technology), was introduced 1998, and now all quality lines have this feature. A SA engineer came up with this incredible idea, in principe, a self lubricating fly line. AST means that silicone is incorporated into the coating mix. Then as time goes by, it leaches out onto the line’s surface. Such a line is much slicker than a line without this feature, and casts much better since the friction in the rod guides is diminished. AST then became AST+ after some chemical sorcery – making the line slicker.
On the front taper the line ID is printed. I really like this feature, but with time the print wears off my lines. Therefore, I mark the weight of all my lines at the end of the running lines. A long black dash – 1” mark means five. A half inch dash means one. I read from left to right — —– becomes 4, —– — becomes 6, —– —– is ten (like the Roman system). This is quickly done and does not wear off. This is a really helpful little trick when you have many lines.
I really like welded back loops on all my fly lines. These back loops easily last the lifetime of the line. I like front welded loops on lines from #5 and bigger. On the smaller lines the loop is just clumsy. The fly line loop adds more floatation, but the butt loop connection adds more nylon (SG 1.2), making it an even game, so the flotation is not an issue. However, the front loop is somewhat ephemeral, and will fall apart some day. There is no getting around this one – you need a strategy to connect your leader to the line, without the easy fix of looping them together.
Tactile reference point
Part of the rear taper of the line is smooth, i.e. there is no shooting texture, and you can feel that. It supposedly helps to identify how much of the line is out. But that does not excite me since the colors are already there. When I used this line in Iceland last fall is was so bloody cold that I could just about feel the line, the tactile reference point was not felt.
Cost and quality
Fly anglers can become very excited, bordering on agitated, about their fly rods, and then have no clue about their fly lines. As I gain experience teaching casting, I am now in the camp that maintains that the fly line is the most important part of a fly angler’s setup. I like everything about this fly line. For dry fly trout angling it is fantastic. For salmon, when you are using small flies, it is superb. Furthermore, it is true to the AFTMA weight standards, i.e. a seven-weight line is exactly 185 grains. The front taper is twelve-foot long, so if I were to use very heavy flies, I would switch to the Anadro line, with its much shorter and powerful front taper. When you go through the points above, you realize that there is some serious engineering behind this line. SA maintains that this line is very durable (at the very least double lifetime or much more), and will last without loosing its characteristics. I have not owned one long enough to know that. However, the quality of this line is second to none.
I do not much like lines that are made stiff, hence coliy, or the so called tropical lines. It is just my peccadillo and I am the one living in this body. I left the Amplitude Trout and Anadro lines out in the heat (90 F) here in the Florida Panhandle. After that they were a tad limp, but when I still could cast the whole line, I can see no reason to have tropical lines in my arsenal anymore. Saves a bundle right there.
This line retails for $129.95. Is that prohibitively expensive? That is up to debate, and each of us might reach different conclusions. If the line lasts as claimed, its price is suddenly very attractive, for instance. Whatever your take is on the price, there is no better line in its class.

A floating fly line is made of a braided nylon core, onto which PVC is added as a coating. The specific gravity (SG) of nylon is 1.2 and the SG of PVC is 1.4. With those numbers the line should sink. So, why does it float? (For perspective; Aluminum has SG of 2.7 and marble for instance has SG of 2.6)
Specific Gravity / Relative Density
SG over 1 – denser than water (sinks), conversely SG less than 1 – less dense than water (floats). Here is a simple review –
When you are dry fly fishing you need a fly line that floats. Now that was an intelligent sentence. We like to turn over the leader gently, and that means a thin tip. If the line tip sinks, it will pull the leader butt under. Conversely, if the leader butt pulls the line tip under, it sinks. The line’s tip SG is ~ .85 (see later), it wants to float and will, unless something makes it sink. The leader has a SG of 1.2, and once under water, the whole leader system will drown, taking the fly under. The critical (to floating) part of the fly line is the level terminal tip. It is easy to make sure that the thick belly of the line will float like a cork. However, the fly line tapers and ends in 6” of level tip. Now the diameter of the tip is 0.037” and the relative contribution of the coating is much smaller than in the belly part.
The Core and the PVC
The core is braided multifilament nylon. In between the filaments, which are braided into hollow strands, there will be some air, and the coating traps some air around the braid in the manufacturing process, which is the big contributor of air, bringing the SG of that part to just under 1.0, but not much. In 1954 SA added air bubbles to the PVC coating, and lo and behold — the new line floated. This is considered to be the first modern fly line. Subsequently in 1959, SA introduced micro-balloons into the PVC coating. The SG of the PVC coating of the level tip is nowadays 0.85. So, that takes care of the SG problem.
Any body placed in water will displace a certain volume (remember Archimedes?). Archimedes’ principle
states that the upward buoyant force, exerted on a body immersed in a fluid, is equal to the weight of the fluid that the body displaces. So, now the line weight is less than the weight of fluid displaced, and the line floats. The SG is a reflection of Archimedes’ principle in relation to water’s SG set as one.
Surface tension (https://en.wikipedia.org/wiki/Surface_tension) is the tendency of liquid surfaces to shrink into the least surface area possible. We all have been shown iron needles floating in water, because of the surface tension.
Water’s surface tension is high. The PVC on the other hand is hydrophobic. By certain chemical additions (don’t know which – probably secret) to the lines’ surface, the hydrophobicity of the PVC can be increased. The silicone that leaches out of the line increases the hydrophobicity of the line, increasing the floatation, too. We can also apply silicone to our lines with good effect. We all know that cleaning our lines makes them shoot better and float better. A dirty line is just less hydrophobic – so now go clean your lines and buff them with silicone.
We know that a small piece with a bigger surface area will float better, because of the surface tension. The line’s surface area can in fact be increased by texturing. This is very similar to the dimples on golf balls. So, the surface area in contact with water is increased, and the textured line will now float higher.
The “Lotus effect”
https://en.wikipedia.org/wiki/Lotus_effect – Scientist have noticed raindrops falling on lotus leaves, and then just roll off. It turns out that the surface of lotus leaves are hyper-hydrophobic. The reason is that on the surface of the lotus leaves there are microscopic pointy structures, replicated millions of times. Engineers can mimic that effect by manufacturing lines with a rough surface (Sharkskin was the first in 2007). This surface is rough on the fingers. However, the hydrophobicity of the line can definitely be effected by manipulating the line’s surface.
Simply put, floating lines are lighter than water, and are hydrophobic, so they sit higher on the surface than they would if hydrophilic. Lines can be made hydrophobic chemically and/or mechanically.
Saltwater has a specific gravity of 1,024, so it is denser than freshwater. This allows us to construct a floating fly line for the salt, which can have denser coatings (thus thinner). SW lines’ slightly denser coatings make them tougher (PVC is weakened by most additives), and a bit thinner, which improves casting, i.e. less wind resistance.
To wrap it up
Shape of line and leader
Before we leave the floating line we need to look at shape. I have owned lines (and you, too) that look like a “slinky” when they come off the reel. It is a floater all right, but in this configuration it will sink. The part of the line that is above the water will push the bottom of the coils under. Once a line is subsurface it no longer has the benefit of flotation by being hydrophobic, now it is repelling water in all directions, not just from the bottom.
So, STRETCH your fly lines before you start using them. The same must obviously apply to your leader, so stretch that too while you are at it.
The line leader connection
If the water surface is calm, it is easy to get leaders to float, but we rarely have that luxury. Chop/turbulence causes parts of the leader to sink, and it is not coming back up due to its SG (1.2). It’s easy to float a 6X tippet leader (0.005”), not as easy to float a .030” tippet. For best floating performance, it is very important that the leader especially the butt, is stretched straight (same reason as for fly line). Then dress with silicone line dressing. Remember, there is no silicone leaching out of the leader, and there is no texturing magic there.
The line/leader connection is important too. For lines with very little tip flotation (2-3 wt.) use a 2-turn needle knot to connect leader butts. Heavier lines have more tip flotation, so there are more options. Then there are anglers who use a 7 to 9-turn nail knots “gooped” up with lots of adhesive to make them stronger. These knots sink like a rock, and once the knot is submerged, the whole enchilada sinks. Remember, adhesives can’t make nail knots stronger, they are compression knots. If tied “neat” and pulled completely tight (rare), nail knots can be VERY strong. When the tip end-loop is clipped off delicate lines (I prefer that), it does expose the hollow core of the line, and a bit of water can wick in. Some anglers put a small drop of some sort of waterproof adhesive on the cut end (careful re SG), and that works for a while. Properly tied nail knots (meaning, pulled completely tight) will prevent water from entering too. But even if water does get in it won’t wick far and casting the line tries to force the water out, therefore it shouldn’t become a big issue.
Finally, pay attention to the material you are using. To recap — nylon has a SG of 1.2, but fluorocarbon has a SG of 1.8. Therefore don’t use Fluorocarbon with dry flies, and expect it to float.
When it comes to leader build you need to be very careful. Much is written on leader build, and everyone is THE EXPERT. Don’t get sucked into the black hole of fly fishing leader literature. It only needlessly confuses you and can get terribly anal, causing decision anxiety and leading to a case of fishing paralysis. Pay attention to the three basics: the butt size, the tippet size, and finally, your middle piece/pieces. So, keep it simple, and you will be fine and enjoy your fishing more.
So, here is my attempt to explain and simplify how to understand what a leader is, and how you can subsequently build one yourself, even if it is totally unnecessary, without suffering a nervous breakdown. If you understand the principles, you can build one to fit all your fishing circumstances. A functional leader can be built out of 3-4 (or more) separate mono strands of decreasing diameter. Just consider the butt end, the middle part, and the terminal portion of a leader, i.e. 3 variables.
When you understand the principle – you don’t need any recipes.
Now, the length of the three parts in proportions (%) can vary. Charles Ritz advocated 60/20/20 as a good proportion. That build is quite powerful. For a leader that is not too delicate and not too powerful, Bruce Richards suggests 50/30/20. If you want your leader to be very delicate just increase the length of the terminal tippet, if a more powerful leader is desired, then shorten it. If you don’t want to lengthen your leader, but keep it delicate, you just shorten the first segment (40/30/30 or 35/35/30 for instance). Ritz’s and Richards’s recipes are applicable to standard length leaders (9-10 feet). For longer leaders the butt part needs to be longer. If you apply the 50/30/20 formula to a 15′ leader you get a butt that is too short, taper and tippet that are too long for mortals to cast easily, thus 60/25/15 would work better. For very short leaders the profile is less important. They are all used for streamers, so no delicacy is needed, and because they are short and the flies are big there is always plenty of power.
LEADERS BUILT FROM MONO
As you gain experience you might start to build your own leaders. To build a leader from mono you need knots. Obviously, now the connecting knots are the weak links. Two knots are the weakest links and must be strong (well tied): the one that ties the fly to the tippet and the one that ties the tippet to the rest of the leader. All the rest of the knots are tied in much stronger material, even if “weak,” they will be much stronger than the critical two. So, what knots to use is partly determined by that. Most anglers would use blood knots, because they are the neatest and pass through the guides best. The last two knots will probably be something different, for strength. There are certain types of knots for backing to reel, backing to fly line, fly line to the leader, leader to tippet, and finally tippet to the fly. And how we can torture ourselves with endless drivel on these knots! For chrissakes make up your mind, and just choose the bloody knot type. A plethora of knots exist, and many types of knots do the job. Here is one of the sites that display line to line knots.
Here again, the problem of choice rears its ugly head. So, which knots to choose? Actually, it does not matter much which type of knots you choose, just choose one for each job, and stick with it.
Building a leader
For a floating line
Let’s consider a 10′ leader. The butt size/diameter needs to match the fly line diameter tip (70%). I am using a 5# line with a tip diameter of 0.038”. That calls for a butt diameter of 0.026” (0.038” x 0.7 = 0.026”). Therefore, the butt part is already dictated by your fly line. You can influence the power of your leader by adjusting the length of the butt part. Six feet (Ritz’s recipe) will get you a powerful leader, but a shorter one, say 5 feet (Richards’s recipe) will yield neither a powerful one nor one too delicate.
I consider the 50/30/20 to be a standard leader.
So, we go with 5′ of 0.026”. Now, skip the middle part for a second.
We are using a normal #10 fly. We use the X rule (divide the fly size by three – that’s your tippet X). 10 / 3 = 3 circa, so now we go with a 3x tippet. Rule of eleven states that a 3X tippet has a diameter of 0.008”.
Let’s use 2′ of 0.008” for the tippet.
Now we have five feet of 0.026” butt section,
and two feet of 0.008” for the tippet.
That leaves three feet, and we can use a 1.5′ mono of 0.020” + 1.5′ mono of 0.012” to bridge the gap.
Generally when we are building leaders, and the differences in the diameters of the mono make it difficult to tie together, just use two or three sections of mono to step it up or down. That adds one more knot, but not in the critical part, i.e. the tippet of the leader.
The leader you need is dependent on its use. For instance, you need more power to cast a heavy fly than for a dry fly. Your choice for length of the butt section will influence the power of your leader. Your casting abilities play a role, too. Beginning casters need more powerful leaders than elite casters. Weather also plays its role. On a windy day (and most are) you need a more powerful leader. Leader length is a factor, too. Long leaders take much more skill to cast than shorter leaders. I would advise beginners to go for powerful leaders – you can always dial down the energy of your cast.
To put it super simply, the butt length decides the power, the tapering part helps bleed off the energy of the cast, and the tippet needs just enough energy left to turn the fly over.
For a sunken line
Sunken leaders don’t need to be very long, but must have enough mass to temper the line turnover. I recommend about 5′ total, 24″ of heavy butt (at least .026″), then 18″ of maybe .020“, then 18″ heavy tippet, 10-12 lb. test at least. Not elegant (elegance not needed), but works both for casting and fishing. Most people don’t use butt sections that are heavy enough. Butt diameter of 0.026″ is a minimum to temper the line turnover.
Level leaders are only for idiot savant casters for the reasons stated below. An idiot savant caster can use just about anything as a leader, but the rest of us CAN’T.
It is possible to use a level leader from the butt to the tip. We know that the butt part needs to be 0.7 of the diameter of the fly line diameter tip. Let us imagine that we need a tippet with 0.026” for our saltwater line. Take a look at the table below for saltwater tippets. (Incidentally, the tippet has no clue where it is, neither do lines nor rods for that matter. I use my freshwater lines in the salt because I like casting them.) Now you are left with a whopping 50 lb. tippet. Perfect butt size but few are interested in tying a 50 lb. tippet to a fly. The hook to be used must furthermore have an eye that matches the level leader. Additionally, now the leader is the strongest part of the whole casting system. That is potentially unsafe, if you need to break off a fish* (a story on that below).
I have a #6 line called TROUT with a tip that measures 0.039.” Its diameter calls for a 0.027” tippet. If I go with the 50 lb. tippet (butt diameter 0.026) the resultant knot could turn out to be bigger than the fly itself. The trout tippet lineup (above) has its thickest tippet at 0.013 or only half the diameter needed. Because of all those issues I strongly advise against using level leaders. If you only have tippet material left and must use it, choose a diameter between the butt requirement and the fly size requirement. Like most compromises it works, but not well.
In a blog like this I can’t list leader recipes left and right.
I would like to draw your attention to Keith Richards’sHow to… Design Your Leaders Streamside.
Keith’s recipes are based on break strength and are undoubtedly good designs. But remember that it is mass that makes the leaders work, not its break strength. If Keith used older, low tech monofilament the diameter would be large (the mass, too), and surely correct. But if you make your leaders out of newer, high tech monofilament, your diameter/mass will be much lower and the leader butt, and the mid-section will be too light. Use Mason Hard Mono or Scientific Anglers Absolute Hard Mono to guide you to correct diameters of butt and mid sections.
STEINI – A PRINCIPLED ANGLER – CLEAR PRIORITIES
* When you are fishing the blue-ribbon salmon rivers of Iceland, there is a tradition to serve a drink when you return to the lodge for your meals. Punctually at 2pm and 10pm you return for the meals, and get your reward. Steini, one of the great characters of Icelandic fishing lore, was once fishing in Vatnsdalsá. Steini was a very accomplished salmon angler and had frequently caught big salmon (20lb. plus) in Vatnsdalsá. Those big fish are not subdued quickly, if at all. One day he was fishing just before the noon break, and a big salmon nailed his fly and jumped. No doubt – a very big fish was on. Steini went ashen and muttered “Another bloody outsize fish. I just can’t stand this. Takes forever to land the bloody f…….” Whereupon Steini straight-lined the salmon, gave a hard tug, and broke the fish off. Steini taught me a lot, and I cherish his memory.

Leader no III.
There are lots of companies offering their leaders. It isn’t practical to go through all of them. I choose to portray some of SA’s leaders simply because I know exactly, what I am getting when I buy those. The diameters (butt-tippet) of each leader is clearly stated. If the diameters are not stated, I will not buy that leader. All companies list the break strength and length.
We have defined the three parts of the leader. First comes the butt end, which needs to be 70% of the diameter of the floating fly line tip. The middle part then tapers, and the leader ends in the leveltippet. The tippet needs to match the hook size to a degree. Modern commercial leaders have become fantastic. They are offered in various lengths, tippet/butt diameters, suppleness, and break strengths. You can find a leader for all your fishing needs from various companies. I strongly advise beginners to use the commercially available leaders at the outset. Mono has become much stronger over the years, and the quality of the leader material has improved. If anglers can’t find a leader that works for them – they need to fix their casting!
Ready-made leaders mostly come with a pre-tied loop on the butt end. When you use such a ready-made leader there is only one knot to worry about — the one for the fly. There are certain types of knots that work well for backing to reel, backing to fly line, fly line to the leader, leader to tippet, and finally tippet to the fly. The knot to learn first is therefore in the terminal connection category.
This site lists 34 terminal knots that you can use. There are undoubtedly many more. To tie the fly onto the leader, I use the classic Clinchknot and sometimes the Uniknot. It does not really matter which one you use if they are tied badly! Here again, the problem of choice rears its ugly head. So, which knots to choose? Actually, it does not matter much which type of knot you choose, just choose one for each job, and stick with it.
If you come to a fork in the road – take it (Yogi Berra).
To give you an idea of ready-made leaders you can buy – let’s start with the Trout Leaders. It is simplest to display the information in a table. It is much easier to visualize that way.
So, 22 different trout leaders are available! You don’t really have to make your own. Below are pointers on which ones to use and when. Remember, for beginners the shorter leaders work best. As your casting improves you can cast longer leaders, but they are rarely required.
When and why would we choose a short or long leader? Usually the reason has to do with visibility. If the water is murky or it is night-time, very short leaders and heavy tippets work fine. If the water is gin clear, the sky bright and cloudless, the water calm, and the fish are biting, and enjoy great visibility (think bonefish, or trout), then you need a longer leader, and longer lighter tippet.
Seven feet six-inch leader.
1. Short, powerful and ideal for casting big/heavy flies/fly. Just remember to open your loops when delivering the heavy load. On a windy day this leader can become a great trout leader. This length leader is the easiest one to cast.
2. The butt diameter is the easy part – it needs to be 70% of the diameter of the level tip of your terminal floating line.
3. The break strength is decided by the size of the fish, and the size of the fly you choose (#fly divided by 3 – indicates X size of your tippet).
1. This leader length can be viewed as the standard-length leader. This length is my default and is practical in most situations. Just a tad more difficult to cast than the 7.5’ leader for a beginner.
2. The butt diameter is easy – it needs to be 70% of the diameter of the level tip of your terminal floating line.
3. The break strength is decided by the size of the fish, and the size of the fly you choose (#fly divided by 3 – indicates X size of your tippet).
1. This leader length can become useful in situations where the fish enjoy greatvisibility – clear water, mirror surface, sunny day. If the trout are finicky an eleven-foot leader places the end of the fly line further from the fish, which can become advantageous. However, those extra 2 feet will become much harder to cast for a beginner.
2. The butt diameter is easy – it needs to be 70% of the diameter of the level tip of your terminal floating line.
3. The break strength is decided by the size of the fish, and the size of the fly you choose (#fly divided by 3 – indicates X size of your tippet).
Fourteen feet leader.
1. For the idiot savants of fly casting, NOT to be recommended to beginners
Salmon, Steelhead and Seatrout
For Icelandic readers – steelhead is a seagoing rainbow. For American readers – seatrout is a seagoing brown trout (in British English). So, here we have five nine-foot leaders, and three twelve-foot leaders. It is enough for me. These anglers don’t use the X system, only worrying about the break strength of the tippet and the leader length. Nine-foot leaders are the standard. In low water situations and when the visibility for the fish is good, twelve-foot leaders are handy.
Here you have five different leaders to choose from and that’s plenty in my book. Break strength is the all-important factor. This crowd does not pay enough attention to the butt size of their leaders, but they should because the flies are often heavy, and you need optimal energy transfer from the fly line to turn the beasts over. However, these leaders have the optimal butt diameters.
The red thread for all the leaders above
I noticed, when looking at these leaders, that all these leaders have relative thick butts. By relative I mean in respect to the butt diameters I was used to using chasing trout in Iceland twenty years ago. The butt diameters are not a coincidence. This manufacturer knows the importance of matching the leader to the fly line likely to be used, and these leaders cast very well with the correct line.
You also have noticed the marketing “trout leader” “salmon leader” “saltwater leader” terms. These are all high-end copolymer nylon with a relative density of 1.2. They have no awareness and have no idea where they are. The fish don’t care what we call those leaders either. So, you can use them whenever, wherever you are fishing, if the break strength and diameters and length is ok. The leaders above are made to be used with floating lines.
When you are using lines that sink (sinking, sink tip, or intermediate clear tip lines) you do not need a long leader. Sinking lines can have a very heavyterminalend, plus are often used with quite heavy flies. These leaders work very well, but remember to change your casting. Sinking type lines should not be cast as floating lines. Open up your loops and minimize your falsecasting. On each forward cast lay the line down for an instant, then backcast and gradually shoot the line out. This type of leader can be used to an advantage with floating lines too. If you are casting a very heavy streamer you can use a four-foot leader to ensure that you can turn the streamer over. Floating lines with a clear floating tip do not need long leaders – this leader works well with such a line.
But which one ……………?
I have tried to explain the fundamental basics of how you choose your leader. When you understand those, you can choose which leader to use in the different scenarios you encounter. So, the answer to the question above is —– usethe right one. Remember, that the leader you need to use is dependent on your casting abilities, and to a degree on the weather, too. In bad windy weather go shorter. If there is great visibility for the fish, then go longer but never exceed your casting abilities.
https://everyjonahhasawhale.com/wp-content/uploads/2020/07/IMG_1338-scaled.jpeg17072560Jonas Magnussonhttps://everyjonahhasawhale.com/wp-content/uploads/2019/03/FFI_9846_Logo®_Casting_Instructor_CMYK-600x476.jpgJonas Magnusson2020-07-26 17:26:112023-02-27 07:16:59READY MADE LEADERS. Leader no II.
The leader is probably the most overlooked or misunderstood part of the fly casting system. It is impossible to do the subject any justice in one blog, therefore I will parse it out. This part covers various generalities on leaders.
Much is written on leaders in fly fishing. A Google search – “fly fishing leaders” – yields about 17,600,000 hits (0.91 seconds). That’s a lot to chew through, and if you missed the 11,111,00th you are in serious trouble. Some pieces are of course excellent, and others are less so. However, leaders are often made out to be very complicated, when they are not. Remember, the leader is a continuum of the fly line that happens to be clear. The front taper of the fly line tapers down to dissipate the energy of the cast, but should leave just enough energy to turn over the leader and the fly. That’s the leader’s function (dissipate energy – turn over fly) – there is no mystery. The standard leader is 9′ long, starts with a butt end, and ends after tapering, in the now thinner tippet end. That’s it – that all there is to it.
When ruminating on leaders, we must make clear, that they are caster dependent. The longer they get, the better you must cast, and the more delicate leaders require better casting. Casting is always a part of leader design. So, remember the leader you use must match your casting abilities. Those who recommend a certain leader, should also state for whom it is intended. If a leader is very long and delicate, it is for the idiot savants of fly casting, but they do not need any help for sure. Our recommendations are for beginners and average casters.
The leader you use trout fishing is also dependent on the general visibility of the day. A calm day with no cloud coverage and clear water, means good visibility for the fish, and calls for a little longer leader. On a dark rainy day the leader can be a bit shorter. The mass of the fly used is very important. Small dries can be cast with delicate leaders whereas a big weighted Wooly Bugger needs a much more powerful leader.
Some housekeeping before we dive into it. A commercial leader comes in one piece. The thick first part is the level butt, then we have the mid-section or the taper, and finally the level tippet. The leader starts out level, then tapers down, and then levels out again. As you change your flies the tippet or terminal portion of your leader gets cut, and the leader shortens. Therefore, you carry a spool of mono of similar diameter to the tippet, and tie in pieces to lengthen the leader again. Mono just means single stranded, but the term has drifted (languages do that) to mean nylon in fly fish speak. Fluorocarbon (also mono) is also used as tippet material, often just shortened to fluoro.
Tippet – The rule of eleven
The tippet material is loaded onto spools, and marked with its breaking test – 5 pound or 10 pounds, etc.- and the diameter of tippet which is far more important. Then there is something called X, for instance X, 2X or 5X stamped on the spool label. This X system is used to indicate the diameter of monofilament lines. This X denotation comes from the past like so much in our sport. Leaders were made from silk worm guts. The segments were then drawn through dies that shaved off a little bit every passage. 3X had been 3 times through etc. The higher the X number the thinner the tippet.
Now the standard is set so that 0X is 0.011 inches thick. Subtract the number prefix to the X from 0.011 to find the diameter of the tippet – for 1X we go 0.011 – 1 = 0.010 etc. Take the 2 numbers, add together = 11. Another way to explain this is to say the X rating plus the diameter in thousandths will be equal to 11. (5 thousandths (.005”) + 6X = 11. 3X + 8 thousandths (.008”) = 11). Now, the various sizes can be found in the table below. Of course the diameter of the tippet is also stated making the x system redundant but the “trouters” love it and therefore it stays. The “salters” only pay attention to the breaking test of their tippet when they should be paying attention to the diameter too.
Mass or break strength
Tippet material has evolved and become very strong. Now for instance, you can get tippet material with 0.011” diameter that has an impressive 16 lb. break strength (diameter of “old tech” 16 lb. Mason Hard mono is 0.020″). Its density has not increased – it is still the same. The mass of such a piece of tippet is therefore smaller than the “older” tippet. However, the turnover of the leader is dependent on the MASS of the leader NOT the break strength og the tippet. Therefore, the diameter (better indicator of mass) of the tippet is the all important factor, not the break strength, when building leaders or adding tippet to a leader. We should emphasize that tensile strength of sections of leaders are unimportant EXCEPT for the tippet, the weak link. Pay no attention to the tensile strength of butt and taper, it will lead you astray, the mass/diameter rule is the important one!
Pay attention to your butt size
So, in the last blog (see below), I explained the importance of having a thick butt on your leader connecting to your fly line. Approximately 70% off the diameter of the tip of the fly line is the goal for the butt’s leader. We arrived at the 70% figure by dividing the relative density of the floating fly line tip or 0.85, with the relative density of 6/6 nylon or 1.2 – 0.85/1.2 = 0.70. This applies only to floating lines. The relative density of the tip of sinking lines is much higher. Therefore open up your loop to minimize the kick, when casting sinking lines. So, it follows that the meatier lines need leaders with thicker butts. You can easily measure the tip off the fly line with a micrometer. The butt diameters of ready-made commercial leaders is now generally of the right size.
Purpose of leader
What’s the purpose of the leader? To deliver the fly, and dissipate the energy of the cast. That’s best achieved by tapering the leader, insuring just enough energy to turn over the fly. Ready made leaders start level, then they taper down and level out again. If you are casting as hard as you can and can’t turn over the leader you need to shorten it and/or use a lighter fly.
The leader ends where we tie in the fly. Not rocket science exactly. But it is obvious that we can’t tie a very thick tippet to a small Collie dog. Conversely, we don’t tie a 3 lb. tippet to a monstrous ten-inch fly. Therefore, it is clear that the tippet size must match the hook size to an extent. You can also divide fly size by 3 and that’s your X size. Adjust up or down 1 size depending on conditions. The recommendation for the tippet size and hook size is more fluid than the recommendation for the butt size, but you’ll get the idea. As you bumble along you get a feel for the size of tippet to use with the various hook sizes.
Light lines can’t cast heavy flies
Some fish (bonefish and salmon for instance) take flies that could easily be cast with light rods. However, you do not want to deal with a salmon equipped with a four-weight rod. Same goes for bonefish. The bonefish flats are wind swept, and you just need heavier lines because of that. If the fight gets prolonged, a shark will eat the exhausted bonefish for sure. It is super important to remember that you can cast small flies with heavy gear, but can’t cast big flies with light gear.
