RE: Quick spin & whisker biscuit
Quick spins dont have to have very much offset at all and shouldnt use helical on them. The biggest problem with quick spins is that they are allot softer material and less stiff than blazers or predetor vanes. Im not sure about the new wisker bisquites but the old ones would tear the quick spins up after just a few shots, make them all wavey and almost melted looking.
