I have had super results from the G5 T3's Taken two bucks with them and both have crashed in site and hearing of me. They both was completely open going in and coming out ,1.5 inch cutting diameter , They open differently from others is why i prefer them Plus 100% steel , this years buck i busted ribs on both sides and no damage to the head , due to all steel construction. I do believe in this head. Of course bow hunting is a game of inches and the shot placement has the most to do with a quick kill no matter which head you sport.
