If you are concerned about penetration a Hunter's Head (now from Three Rivers) sharpened Mussato style has proven very effective for me for a number of deer. I shot a deer with an original last year along a switch grass field. Normally I would go for a 150 wide Deadhead in that situation, but this one caught me by surprise. A lost arrow pass through and the deer went down quickly and in sight with a gushing blood trail that I didn't need to follow. Of course, I was not using anything like a Holy Grail, just a 50@26 duo shooter JD Berry.
