bigbulls, Years ago I shot recurve and strings were a big advantage. I started to make my own with the help of a fellow club member that was experienced. Brownell had all kinds of materials available that many string makers did not use. You name it, I tried the material. Probably the best for not stretching was the Kevlar. The string, when jigged properly would not stretch at all. The problem was they only lasted about 300 to 350 shoot before letting go without any notice. There has to be a little rebound in the string or it becomes dead. I don't know how to explain this situation, but a fresh string seems to work with and complement the limbs. After shooting the string for a long time it's like the limbs are doing all the work and string is just, well, dead. Hoyt's using the Brownell D-75 strings and to be truthful, I can't do any better with a hand made unless I want to change strand count or serving material.
