Depends on the arrow/bow tune but I like to "correct" the arrow as soon as I can with fletching.
Lot of variables here, type of rest,arrow spine,bow centercut,release and one's own form comes into play.
Fletching is not suppose to make a difference because of arrow parodox,but I believe is does in most.
I choose 4 fletch 60/120 4" at a small angle and helical. This works best for me. Second, 3 fletch with 5" shooting with cock feather in.
I know I did'nt help much but someone once said the arrow is more important than the bow.
