Cooked a 6 lb boston butt today. Rubbed in mustard and rub last night and let sit overnight in the fridge. Smoked in apple and hickory wood until it reached 150 internal temp. I wrapped in foil and moved to the oven as I had some other things to do instead of tending to the smoker all afternoon. I did put a bit of apple juice into the foil when I moved to the oven. Left it in the oven until 205 was reached. All temps, smoker and oven were 225-ish.
Ended up with almost a 1/2" smoke ring and tons of moisture all the way thru. Going to be good eats for a week now.
Also cooked a 3 lb slab of babyback ribs, used a different rub for this. Less black, and more spice. I used the 2-2-1 recipe that Jeff mentions, http://www.smoking-meat.com/august-25-2011-smoked-baby-back-ribs. Worked to perfection, I stuck pretty strictly to the 2-2-1, although he says you can play with it a bit. Will definitely be more of this soon.
I am a rookie...only having a couple of smokes under my belt, but both of these turned out amazing!
