Well, this thread got me experimenting with fletching, 2″, 3″ and my old standby 4″, all shield cuts. I see no difference in flight characteristics at all, with broadheads or fieldpoints.

But I do have one question. Are the flight characteristics going to be different in the wind? It would make sense to me that because of the smaller surface area of the short feather they should be affected less than a larger feather… but who knows? Anyone have any experience with this?
