I will not shoot a broadhead tipped arrow with less than 12% FOC. IMO it gives you better conrol and better groups. I also think it will improve your penetration slightly. There are no shortcuts in adding more FOC. Lighten up the Fletching, or add Weight to the front. Weighted inserts, heavier broadhead, or brass inserts. It just depends on how much you wanna try to get. The new FOC shafts will also help. If you ever buy new shafts
