Doctor, first of all, thank you for being gracious about accepting constructive criticism. Dozens of years of judging experience can be tapped by exercises like this.
It's hard to symbolically pull your pants down like this and ask for people's opinions. Looking through some of my old presentations, I have some that, in the heat of the moment, I thought they looked smashing but when viewed later objectively, looked like badly crafted ransom notes put together by some ham-fisted moron. It's even harder to admit that ham-fisted moron was me.
As others have said, unless the rules mandate to put in multiple cuts - or, if all are equally good, in your opinion - load the box only with what you feel looks and tastes best. Backyard or Pro division, judges are giving to give you the benefit of the doubt when there is a quantity of meat in the box. When you put more than one cut in a box, you are effectively competing against yourself. The bad will always bring down the good.
Thanks once again for being brave in soliciting others' opinions. We really do want to see you challenge yourself, raise the bar with your presentations and succeed.
