I won't hardley shoot a bow if it won't accept FF type materials. Dacron drives me nuts, with the stretch. The one exception is a bow I was given--a "fake" Choctaw, made by Jerry Pierce's son-in-law with Jerry's materials on Jerry's presses. It was given to me by one of Jerry's sons, and I promised I'd try to take some game with it. The good thing is it's a lighter draw weight and doesn't stretch the string much.
I like FF type materials because they are much tougher, and have much less stretch and creep. I don't like the new fad of "tiny" strings because you loose those properties for the most part with them.
I've learned that how the string is made, now many strands, the material, nock fit, tuning, etc. etc. etc. plays a major role in how it sounds and feels. I even use Dynaflight or 8125 on my selfbows. I was just out back shooting my new Eric Krewson selfbow with the new 8125 string (12 strand) I made for it--the two guys visiting were amazed at how whisper quiet it is.
My point is there's a lot more to how a bow shoots, sounds, and feels than just the string material.
