FWOW, I've been shooting BCY 8125 which I believe is very very low stretch and very high speed on all my bows, with the only exception being the oldies that I DIDN'T build.
I've got endless loop 8125 strings on several board bows form red oak, which have only hardwood tip overlays 1/4" thick. They range from 25#-55# and I've had no problems. One of them is a lumberyard takedown bow, the one shown in my 'misssion 'red oak' impossible' post which is all red oak, riser limbs and all. Uses cheap cabinet bolts and inserts to hold limbs on and draws 40#.
I have a dacron string on my 45# eastern red cedar selfbow but thats only cause the jerk who made the string wouldn't keep his thinking to himself and delivered me a dacron string even though I ordered 8125. I've shot it and tuned it with 8125 and had no problems. It has only ERC tip overlays.
