I shoot mostly 5" feathers in various styles [P&Y, shield, etc} I recently bought some arrows off a trade blanket that were fletched with 4" feathers and they seemed to shoot just fine. I would definitely continue with 5" on broadheads but thinking of going to 4" for target/3-D shooting. Figure I might be able to diecut 2 useable 4" feathers from a whole one.Any comments from those who have tried this before or currently shoot 4". Shooting recureves mostly and my longow occasionally. Thanks for any input.
