RE: Rookie question
Actually, I believe Fred Asbell recommends shooting your arrows cock feather in every few shots just to make sure there is no difference should you in haste do so in the hunting field.
I have likewise found little difference except for wear on the feathers and regularly mix cock feather in during most shooting sessions and stump shooting.
