Stuffing the smoker for Father's Day

Nothing like the 100+ pounds we smoked for Memorial Day for that 200 person party. Not 5 kegs either. Just a little get together with 8 or 10 people. I never smoke unless i fill the smoker so I'll be stocking up the freezer with the leftovers. I haven't had beef ribs in a couple of years but they should be tender after 10 or 12 hours. I also picked up an 8# pork butt, a 10# brisket and some baby backs. I'll be using plenty of apple wood this time for the smoke.
Whose got a good pulled pork sauce recipe. I'm just not satisfied with just BBQ sauce, it's missing something, maybe the vinegar. BBQ pork sandwiches are great but it's different then pulled pork sandwich taste. I don't mind an Carolina mustard recipe either.
