Is there any advantage to shooting a four fletch, 4" long feather to a 3 fletch, 5" feather? This guy at the sportsman show told me that no one ever shoots 3 fletch 5" feathers anymore and that I should change with the times. He asked me why I shoot 3 and I really didn't have an answer other than that, I always have. So do you have 3 fletchings or 4 and why? thanks, Bobby
