Bob, does that mean that the feathers do a pretty good job of folding away? Does that mean that a arrow with more grains per inch will fly better because of the minor disturbance to the feathers? If so what weight per inch is a good starting point? Or an I just being a duffus and who cares about feather contact?
Looking at the right set of drawings it looks like the shaft makes good contact with the bow (I'm guessing from the string rolling off the fingers), is that correct? This stuff is pretty interesting!
