RE: broadhead flight?
Raise your rest a tad. I shoot T-heads and can get them to shoot the same as FP's. At 20 yds they should hit the same. Now MAYBE,at farther distances like 40-50 yds, you could see a deviation vertically between broadheads and FP's due to more drag and the fact that the BH is longer than a FP, pushing the FOC a little farther, but now you are talking about really picky and minor differences.
