Here was my eventually conclusion after doing fat cap comparisons side by side, individually, etc.
I'm just not totally convinced that fat cap up renders the fat into the meat to keep it moist. If you look at the amount of fat in your trap, it's the same. Then again, let's say it does... all that fat in the meat is really not that enjoyable. Some yes... a bunch no. One unscientific test I did was making two butts at the same time in my offset. Each had their own pan. I pulled them each let them sit and then put them in the fridge. Once cooled and the fat had hardened (you know the orange-y solidified fat you see) there was much more of it in the fat cap up... and when I served both... I had a couple of different family members say the fat cap up one was "greasy."
I just think there's plenty of fat already in the butt and along with the collegen that melts away there's enough going on in there. I'd rather protect the meat from too much direct heat by using the fat cap as the barrier.
Now take all this with a grain of salt because I'm sure therea are guys here and everywhere, who do the exact same opposite of what I do and have fantastic results. Great Q is very much about preference, so you just sorda experiment and figure out what you like best. The thing is... it's all good... even when it's not great so there's nothing to loose really by not trying different things and figuring out what you dig the most.

Thanks for sharing your comparison Chris.

It's funny how I've been smoking 'fat cap up' for years and not seeing the obvious. In particular, always leaving some amount of pork/bark on the grill when I've had to rotate top to bottom or even at the finish. I just enjoyed the morsel left behind as a treat. I only smoke quality bone-in butts and shouldn't worry about the level of 'moistness' after pulled.

The conventional wisdom is: in a WSM where heat rises from the bottom.. fat cap down for both butts and brisket. The fat cap helps protect the bottom of the meat from the heat.
Fat does not render into and baste the meat if placed with fat cap up. It just renders down the sides. Fat down also helps your rub stay in tact instead of losing it on the grill rack.

Thanks John, I have seen the light!! What your thoughts on 'foiling'?
