BBQ Pitmasters (Memphis) did some very large butts on the show last night in about 8 hours, well 10 total. 2 hours prep and sit, then 4 hours on the smoke, then 4 hours wrapped. 1 guy re-injected for the wrap. All got their meat up to 195 in about 8 hours.
The judges pretty much raved about all 3, but the 2 time injection guy won.
The week before, the KC guys had all beef, which is much harder IMO than pork. Brisket and Beef ribs can get way off the reservation in a hurry if you're not all over it.
