I'm going to add to my previous comments here. Feathers are NOT more accurate than plastic vanes. Feathers ARE more forgiving than vanes. If your arrows are properly spined for your draw weight it shouldn't really matter what type of fletching you are using. In case you haven't heard or read about it there is a phenomenon called "archer's paradox". Shooting a bow with fingers the string rolls off the fingers. Because of the energy being transferred into the arrow and the amount of spine in the arrow plus the weight of the tip the arrow will flex. The rear of the arrow will flex away from the bow, back toward the bow then away from the bow. The correct spine will have this flex so that the fletching will not come in contact with the rest.
