All I can say is that it turned out awesome! I did end up brining for 8 hours, using the same rub that I posted (with more brown sugar), using the mustard to make it stick, did a 3/4 apple and 1/4 mesquite mix. The times and temps were spot on (even though I did fall asleep and the temp spiked for a little bit LOL). It's very difficult to keep a constant perfect temperature in the smoker when it's 15 degrees outside and the wind is blowing.
After doing this, I can see what you mean about the fat cap. I envisioned this sinewy thing on top of the pork but when it was all chopped up together the flavor that it added was freaking amazing.
