The trick with quick spins is using about 1 degree offset. I've tried them with helical and they shot below my arrows with standard vanes. So there was a little trial and error to get the right results. One of the down sides to the vane is you won't be able to see the arrow, even if they are crested. the little metal wings basically black the arrow out while it is in flight. If they get wrinkled they will make noise (like most vanes), but then again so do Rocky mountian 100's and thunderheads when they are in flight. One thing you'll find out real quick is if you're having any vane contact it will wrinkle the vanes PDQ. I'm using a TT shakey hunter and have no wrinkled vanes. That being said I had a MZE on an Ultratec that was having no problems with real low profile AAE's. Shot a few quick spins through it and wrecked them in less than 5 shots per arrow. Clearance was real tight on this particular bow and it showed. In the end I've decided to go with the quick spins on all my hunting arrows. Great thing about archery is all the choices we have. Would I recommend quick spins for someone else try. Sure because the cost is nominal and there are a few different places that let you buy them in singles. You don't have to make more than 3 or 4 dollar investment and you can form your own opinion.
