Yes, Barry, reading through the thread, the websites, and reviewing several articles have initiated a change in my thinking about knots. I have to give Scheck (see the above thread) a lot of credit. I’ve read many articles and websites, and he is the only person so far who brings up the need to balance tippet and fly knots. He may have picked up on this only recently. A January-Frbruary 2003
American Anglerarticle he wrote mentions the 16-20, Orvis fly knot, and other strong tippet to fly knots, but says nothing about leader to tippet knots. After reading Meck’s June ’04
Mid-Atlantic Fly Fishing Guide article reporting the findings of the Rio tests, I had settled on the triple surgeons for leader to tippet, and the Clinch, the Crawford, and the Non-slip Mono Loop for most of my fishing. Testing tippet knots was the defining moment in my recent thought process. The most important change I will make in the future will be my leader to tippet knot, but more on that later.
First, here are a few preliminary observations from my own knot breaking experiments:
I like fly tying better than knot tying, but the basement’s too cold to tie flies now, so knots will do until this arctic blast subsides. A Piano leg is good for looping the base of a leader for tippet experiments. Cats are naturally attracted to experiments with leaders. It’s even easier to lose hooks in the living room than at the tying desk, so break off the points if you experiment in a living area. Frog Hair is very strong. So is the 16-20 knot, but it is hard (for me) to tie consistently in the 5 wrap version Lefty recommends for 4X and smaller. It also uses an awful lot of tippet per knot. One tier recommends starting with five inches! The very strong Orvis knot is easier to tie consistently, and I can tie it with about two inches of tippet left over. The Trilene and the Seven-turn Clinch, by the way, waste almost no tippet. (In a kind of reverse snobbery I had ignored the Orvis knots for a while; this thread forced me to learn them, and I'm impressed.)
In more detail:
By using two different knots to tie blunted hooks to each end of a short piece of tippet and using pliers or vise grips to pull the hooks in opposite directions, one can productively test knot against knot. I’d recommend anyone considering the Davy knot to test it like this at least five times against the
Seven-turn Clinch knot (not Improved, which weakens the knot), or any of the other knots mentioned above. My understanding from others’ reports is that the Davy is a weak knot that fails more frequently than the Seven-turn Clinch. I’d be very interested in hearing the results.
One way to test leader to tippet knots is to tie 5X tippet to each end of a short section of 4X, using a different tippet knot on each end, for example, an Orvis tippet knot and a Triple Surgeons knot. Then tie hooks on to the ends of the 5X with an Orvis knot and pull apart. When I tried this using 4X Frog Hair and 5X Flouroflex Plus, the Orvis tippet knot proved stronger than the Triple Surgeons, but not stronger than the Orvis fly knot. Many combinations are also possible if you want to find the strongest fly knot that will usually break before your tippet knot breaks. For example, one can use an Orvis tippet knot for both tippets, then an Orvis and a Trilene (or a Trilene and a Clinch) for the hooks.
A couple of days of tying knots and testing them also can teach one a lot about using one’s fingers and how tight to pull knots. In the
American Angler article cited above, Scheck recommends that folks do their own tests with their own tippet material because different brands and types perform differently. I learned a lot about the way I tied knots, and that some needed improvement. For example, I found that I had been tying the Non-slip loop wrong at times, and that the direction wraps are made and how the end of the line passes into each opening is crucial. I also found that, for me, many knots that require loops around doubled line, such as the 16-20 and the Crawford, are best controlled by making the loops between pinched fingers that can hold the loops in place. Slightly decreasing the pressure between the fingers allows one to slide loops into place.
Art Scheck certainly did his homework, and his words bear reviewing. Though I did not test everything he did, each of Scheck’s assertions that I tested was replicated exactly as he described. I would only add the following points:
He did not test the Crawford knot. It tests about the same as the Seven-turn Clinch, and stronger than the Six-turn Clinch, but weaker than the Orvis fly knot or the 16-20 knot. He does not mention the Eugene knot, another knot Kreh considers like the 16-20 knot extremely strong, and to me it appears a bit easier to tie. I’m not sure whether or not to make additional turns in 4X and smaller, though.

The ligature knot did not test stronger than the Orvis tippet knot for me, but that may have been because I was following directions from the sites I found and posted above. It is possible that I was not tying it like Scheck does. I hope I can learn to tie it well, because without it, unless I want to risk leaving tippet in the treetops, even though I am switching to nylon and using the Orvis tippet knot instead of the Triple Surgeons, I’m stuck with Clinch or Crawford fly knots, especially with lighter tippets. A Perfection loop to Perfection loop may be another possibility with nylon tippets. Some claim it tests at “near” 100%, but this claim is also made for the Orvis tippet knot, and my tests replicated Scheck’s finding that both the Orvis fly knot and the 16-20 knot are stronger than the Orvis tippet knot with both nylon and fluorocarbon. In one study the three turn Surgeon’s loop tested at 95% of the line strength and the Perfection loop tested at 90%. It might be good to see test results for perfection loop connections compared to different tippet to fly knots.
I would entirely agree with Gonzo that hooking and playing skills are much more important than knot skills, but with the lighter tippets that are sometimes necessary (though not as often, perhaps, as one might think) having good hooking and playing skills
and a strong light tippet
and the best balanced knot system would often increase one’s odds of hooking and landing a Delaware River rainbow rocket in low clear water, without risking litter, or tiring the fish more than necessary. Under most conditions better knots will make little difference; under tough conditions they may make all the difference. I’ve ordered Scheck’s book to learn what he can teach me about the ligature knot. If I can learn to tie it well, it may hasten my return to nylon tippet material and increase my use of the Orvis, Trilene, and the Non-slip Mono Loop knots for leader to fly.
