i was just out shooting my 82nd, and noticed my string loop was just about shredded. i just bought the bow in march, and this is the second loop i've been through. i figure i'm getting 150-200 shots a loop. my release clamps down around the string, not on it, so i don't think that's the problem. if anyone has any opinions about metal loops, i would appreciate it. i've heard they reduce speed a little, but i'm plenty fast already.
