I have a feeling this thread will take off...
But my 2 cents are this

QDM principles are to pass on young deer, shoot mature does and bucks. It just so happens that mature bucks almost always equal big bucks. If you get into situations where you are shooting cull bucks, and worried about genes,then it's leaning towards QAM. QDM is also about having an age structure that spans deer of many age classes. If all your top end bucks are only 2 1/2 that is not a healthy age structure. Passing on a small bucks=young bucks=allows the age structure to be sorted out with older deer. Shoot enough deer for the land to hold, pass on younger bucks, I don't think its that much to ask, or too difficult a concept to grasp.
