Ok guys, you all saw the form thread I had, and the reason was I was getting some incosistent groups, and that was my first thought. Well, last night I was putting my stuff up and I saw that my new cock vanes were getting a little wavy after not many shots. I looked a little closer and saw black marks. This morning I put lipstick on the vane and shot it threw, and sure enough, had a red mark on the rest. I shoot a Quicktune2000 drop-away with Easton Epics with the 4" vanes that come on them. Its hitting on the left prong on the inside, so I tried turning the nocka little, and eventually just starts contacting the other prong. I know its coming fully up at full draw, but it may be bouncing back up for all I know. Whats a guy to do?
