I smoked 2 butts this past Sunday. I put both on second rack slot from top. Fat up. Dry rub only. Cooked till IT hit 150 degrees then I flipped them over into individual foil pans. Put two tablespoons BBQ sauce, Tabasco chipotle liquid sauce about one tablespoon, and piled a big handful of chopped onions on top. Covered n cooked till 195. Just before falling apart. One I cooked for a friend. Said it lasted 30 minutes on table.
