Thanks NUB, I know what the little holes are for, the cam timing. In fact thats one of the reasons i had the string replaced. I blew the cable and had it replaced, still had good poundage but noticed the timeing was off now. took it back to the mathews dealer and they said the only way they could get it timed was by replacing the string. I guess the new cable and old stretched string would not match up. But ever since the string was replaced now i have less poundage. What the hell??
