personally, it is the FG for me regardless the line poundage and type of fishing method/purpose. weaves of between half of an inch till about 1.5inches depending on type of fishing and targeted species, and of course, the half hitches.
ultimately, i guess it is 'to each his own' when it comes down to friction knots.. as long as it holds and lands the fish, be it the FG (with or minimal half hitches), the PR, or even the Albright, or whatever knot that works for you.
