huntinfool14,
I've had 2 dozen pre-fletched arrows from CX and have over 500 shots on arrows from both dozen and have yet to have a vane rip off. On the arrows with 300-500 shots there is a little black on the vanes but that is it. However, I don't hunt with these arrows because I found they are to noisy on the draw.
