If the arrow is tuned to the bow right I do not think it matters.IMO.
I'm getting fantastic flight with 3 4 inch feathers. However, the bare shaft ain't that bad on its own.
that's a loaded question as other feather dimensional parameters need to be taken into consideration ... and some bows just work better with certain feather dimensions, numbers and placements. experiment!
