I was told you can pick up a few more fps and that it also make your arrow in fight quieter. My broadhead is a fixed one piece, I' m giving up on the mechanical broadheads (I personally don' t trust them). My arrow fight is pretty darn quiet now, I was looking to close my pin gap so I have one pin setting for 25yds. As I posted above, I' m going to fletch up two just to see if it will help out any. Thanks for the post guys and good luck this year. I' ll post my results as soon as I can.
