I like to do a 2-2 5-10 method. LOL. 2 hours smoked, 2 hours wrapped, then 5-10 minutes over high heat to sauce. They have always come out really good. I usually add a little beer when wrapping, so maybe I am getting enough steam to get them done in just over 4 hours total. If I don't wrap then its a crap shoot as far as total time, but I think the end results is just as good. I usually don't sauce when cooking unwrapped, so the end result is a good bark. When wrapping I usually do sauce, so the bark doesn't matter as much since it gets covered with sauce then cooked over direct heat a few minutes a side.
