Ok, this is my 4th or 5th Brisket....It's around 11lbs. using the 1-1.5 per lb. It should take 12 hours or so. Its been 7 hours and 15 minutes and its already at 200.....I wraped it at 170 and was going to pull it out at 190 BUT I want it to be fully cooked. So leave it on or pull and wrap? BTW I tried to keep the smoker at 220. It approached 250 several times when adding wood.. Tip hints ??
