Dont get me wrong Im not knocking suttle T's, Ive heard great things about them. I personaly like G5 strikers myself. All I was saying is if you want really big holes you have to shoot an expandable. I dont like them and wont shoot them for the simple fact like you just said, shoot one into a shoulder and see what happens. Your possibly going to ge complete penetration but the blades will be snapped off in the first shoulder. Fixed blade is definetly the way to go for strength.
