I'm trying to decide which weight broadhead to go with, 125 or 100 grain. I'm shooting a 26" draw switchback, using Gr broadheads, the arrow weight is 376 grains with 14% FOC. Chrono'd this arrow at 70# speed was 252 fps. To gain some speed, I am considering dropping the broadhead weight down to 100 grain, making the total weight 351 grains with a 12% FOC. I'm not shooting mechanical broadheads due to the approximately 55 ft/lb of energy, but I'd like to get pass threw's if possible. Any recommendations??
