I am a fan of feathers, but thought Id try out quick spin vanes. I am impressed. They do improve arrow stability, the only problem I found is that they are not real durable. When I would shot tight groups, they bent up real easy. Some straightened with the hair drier/ heat gun trick, but not all. I will say agian, I could tell a difference in my arrow flight, which was better. My groups also got tighter.

Just food for thougth.
