it makes sence to me but sometimes statistics dont work out in the real world. my brother got some at one of the shows this year and i think he will be using them soon so i will let others know how they fair. the feeling i got was some loved them and others hated them but its hard to change the old ways of thinking. most archery hunters i know dont fletch there own arrows and repairing the occasional loose vane is a chore. i have a jig but hate fletching my own. if they work out for my brother it would interset me . raw shafts are cheaper so it would offset the cost of the turbo nock.
