I Am Current Upgrading To A Mathews Switchback Which Is 33" ATA, Set At 60 lbs And 28" Draw. Manufacture Specifications Indicated IBO Of 318 fps At 70 lbs And 30" Draw Using 350 Grain Arrows. With This Information In Mind, How Should I Go About Determining The Best Arrow Weight? The Bow Is Exclusively Used For Hunting. I Am Currently Shooting Beman ICS 400 Hunters With 100 Grain Broadheads. I Am More Concerned About Accuracy And Energy (Pass Throughs) Rather Than Speed. Any Ideas Regarding Type & Weight Of Arrows Would Be Greatly Appreciated.
