Ha, so I learned:)
Really? Fly guys not trusting nail knots; leaders snap at a perfection loop........ what's going on?
The only time that I had a problem with a nail knot was with a Rio Versatip 9 wt where I had problem tying my butt section onto the T8 that came with the line. The knot simply strip the coating right off. That T8 tip looks and feels different to the T8 tips one buys in bulk. That was 10 years ago and I blame the tip rather than the knot. I suppose if that had happened earlier in my fishing career I'd have thought differently about the knot.
As RalphH mentioned, perfection loops are fine for
butt material. I have never had a problem with it either and I like the fact that the line comes out straight and centered. I do wonder how others use it. Do some of you do a loop to loop with say a 25lb to a 10lb connection? The loop in that case do not sit properly, just wondering........
For a floating line, I stick to a nail knot. I personally feel that the slimmer the profile the better.
