Buddy,
I would be interested to find out if I done the testing of this knot incorrectly or it failed. I thought, 3 years ago, this would be my knot of choice but found out it would not hold or seat on a large diameter wire hook like a #4 or 6. As you tightened it up, it would just continue to slip and not snug up. If you get a chance, could you include larger hooks for your testing to see if maybe I did not tie it correctly? It did seem to work fine on size 14 and smaller.
Thanks,
Warren
Fly fishing and fly tying are two things that I do, and when I am doing them, they are the only 2 things I think about. They clear my mind.
