string stretch and elasticity, that's what matters most to me.
string speed? mass string weight? could care less.
dacron (polyester = b50, b55) has lots of stretch and creep. it never ever goes away, 'cept just before it breaks.
hmpe (polyethylene = d'97, d'02, ff. etc) has lots less stretch/creep, therefore the string is far more stable (no changes in brace height before, during and after shooting).
i use less strands of hmpe not for speed, but to better balance a compromise of stretch/creep. less strands of this stuff is less resistant to stretch/creep than more strands, but significantly more resistant than a wad of dacron all twisted up. as a by-product, noise levels are less with low strand count strings.
ymmv. [/QB][/QUOTE]
Rob- Very true the brace height is more consistent with hmpe, but if you know your brace height, you could check it from time to time. that's what I used to do. Dacron has worked well for decades before the new stuff came out. Also, Dacron will be less stressful on the bow as well, but I know guys don't keep bows that long anyway
I'm guilty of that. I like dacron on my Hills and wood arrows only, maybe it's that traditional thing.
