RE: NAP QUICK SPIN VANES
not worth the money. i tried them, give it a few more shots and they will be so wrikled you wont be able to shoot them anymore. I was refletching my arrows about 2 times a week, got too expensive. They are just not durable. My 2 in. blazers work way better, and are a lot more duable and can stablize a fixed blade B-Head.
