Well, I did my butt a little different, but it's killer. It went a bit faster than the other way, but the results couldn't have been to much better.

I wrapped my butt in foil, and cooked it wrapped for 18 min per pound at 265 (bout 1.5hrs). Then I pulled the foil back and cooked it another 1hr 45min. Moist and juicy with an internal temp about 165. Plenty good to me!!!!!
