OK I did it. A 10.5lb Boston Butt. I put a nice rub on it and refrigerated it from 9PM until 8 AM the next morning. I am still fine tuning my UDS so the cook was between 350-375 and for about one hour it spiked to 400 degrees. It took a total of 61/2 hours. Every two hours I put on 3 parts Apple juice and 1 part Captain Morgans spiced rum on the butt. I did not foil it after it reached 165 like some. When I went to pull it almost fell through my hands. After an hour of letting it set, I pulled the bone with no effort out of the meat. Here are some Q pics
