Just wondering what you guys use to tie on smaller saltwater flies #8,6,4. I have used perfection loop mostly and the Duncan loop on larger flies. The Duncan(Uni-knot) will always collapse upon fighting a fish and can be hard to expand into a loop again. Recently saw folks using the no-slip mono loop on a video. That does not have a tag end protruding at right angle to the knot, if tied properly, unlike the perfection loop. The no-slip mono loop supposed to have a 100%plus strength rating.
