I wouldn't put all my eggs in one basket. Fletch up 2 or 3 with 4 or 5 inch vanes and see if you are happy with the arrow flight, especially with broadheads. Field points fly with most anything if your bow is tuned. You might find feathers stabilize your arrow/broadhead combinationbetter. You'll never know til you try, but 3 arrows are easier to refletch than a dozen if you need/want to.
