Rocket steel head. It has been proven time and time again to be one of the best penetrating and strongest mechanical heads made. Stay away from huge cutting diameters and stick with a mechanical that a moderate cutting diameter for better penetration. Don't fall for the "cutting diameter is everything" BS. It doesn't matter if you cut a 1" hole or a 2" hole... if you can't get through both lungs because you smacked a shoulder blade with that huge broadhead then you are in for a long day or night tracking your deer.
Another good mechanical is the Wasp jackhammer 1-1/4" cut.
