Feathers , no question . I read about the new quickspin vane from nap and thought I'd give um a try . The first shot I had slight contact and a rippeled vane , I keep trying to get that perfect clearance and kept getting contact and buggered up vanes . It only takes slight contact to ruin a vane . Went back to feathers and , no looking back . They are much more forgiving . I was getting contact with a fallaway allso , so thats not my answer .
