I used to use the RP knot. I would tie it in pinch if I had to tie something quickly on the boat. 7 turns is about what I used. I however would break the knot at times. It was probably my fault, because a retie would be good to go.I have been Using the RP Knot
with 7 turns both ways and a
1/2 hitch on each end
with no Failures so far.
I never had an RP knot fail on a fish because I would pull on it good before using it. I do not like the tag end of the RP knot
The FG i like much more. I like the low profile. It has tested very well. No failure on any fish, though I must admit not catching anything over 40#'s since I started using it a few months ago. The tag end is not an issue.
