I had some GoldTip 5575's fletched at a store the other day. I wanted a full helical and they acted like that the small diameter of the carbon shaft would not allow much helical. Sure enough, compared to the ones I already had with a 4 degree offset there is very little difference. I am shooting a drop away rest and would like as much as I could get. They used a JoJan Fletcher, could another fletcher like a Bitzenburger work better?
