I'll keep them I guess. The Goldtips are straighter, no doubt. But I've heard that when you shoot the difference in straightness is irrelevant as the arrow bends when shot. I dunno, or care, I just know I love my epic st's. I try not to get to technical, I believe in the KISS-Keep It Simple Stupid! system. I just thought if I could tighten my groups even better then I might try different arrows but it doesn't sound like I could get it better. Thanks for the advice.
