I'm a displaced North Carolinian, so my vote for pork butt is naturally assumed. Do a couple of butts and make it a big event ... two 7lbs shoulders ougta burn a big hole in 18 hours. Then, through the magic of WSM, smoke, rub, and love of Q, you'll see something on the other side that will bring a tear to your eye and a pang in your stomach.
Rubbed butts ... yep, that'd be my vote.
