what do you guys know about these quick spins. can I shoot a mechanical broad head or not. everyone tells me something different

I shoot Spitfire XP 100gr w/Quick Spins...superb groupings. Haven't had a problem yet and I've used them for the past 3 years.

Quickspins deform way too fast though. The vanes start to get really "wavy" after just a few shots. I use to use quickspins, but switched to blazers and like them much better.

They preform well with both my NAP spitfires (expandable) and the Razorbaks (fixed) but they aren't the best in the durability dept. I'm constantly having to straighten them out because the wrinkle easily. I don't feel that they're worth the $$$ either. I've got a set of Blazers on deck for when these Quick Spins crap out, I'm just hoping I can get through the season without having to refletch everything.

I havent tried them but my brother has, he did'nt like them or feel they was worth the $$$ also, also he said they would tear off easier than normal vanes, probobly from deforming
