Kris, I have cooked Butt HH and found it to be as good as LH. I compete and have done brisket HH several times with good results. I personally am not sure that your average judge will be able to tell the difference between HH and LH. If both come out the same in taste, texture and appearance. Some others will disagree, I suggest you do trials with both methods and judge for yourself before you submitt to the judges at a comp.
Good Luck on the trail.
Mark
