i was curious about the same thing. gibblet gave me lots of choices and i simply dont know...

its gunna be a few weeks till i order so i didnt post yet...but you took care of it for me...

all i know is the factory string on my reflex is shot. that sucker twists about 4x before it hits full draw

im mainly looking for speed, stability and durability in my choice material though...my bow is already slow..plus shooting heavier arrows this year...so itll be SUPER slow..figure if i can pick up some speed that would be GREAT. i know i give up stregnth to get speed though...i rather do it...im careful with my stuff...i mean its a hunting rig...but i will get cut to shredds by brush before my bow touches it!!
