You would probably be alright shooting any of those heads. People preach too much about penetration. Deer and black bear are relatively thin skined and small boned compared to the larger north american big game. If your pulling 69 lbs and generating 60+ ft lbs of kenetic energy out of a well tuned bow you should be fine. A well tuned bow and shot placement are the major players, doesnt matter what head you shoot if you dont hit it in the right spot.
