i hurt mine rollar skating. But had been already torn doc says and i just finnished it off. Never had bothered me at all till i finnally tore it. I used to shoot 70#s also but never again. Got a bow with 50# limbs and maxed out at 53 for hunting. Target bow is about 53 for indoor and bumped it up a couple of #s for outdoor mabe 55 0r 56. thats all i need for me. AC
