Blazer vanes work very well, i tried the cheap way out with the dura vanes and I got cheap results. Blazer vanes are about $7 a pack. They are 2" vanes but they perform very well. My fetcher has a helical twist...it works just fine with my wb q2. Also get you some good glue. I came across some great glue called "Duco cement", I bought it at the Family Dollar Store for another application and decided to try it. It works better than the $5 stuff at the bow shop. I paid $1.25 for it. I'm happy with it!
