Just did my third brisket... this one was just < 12 lbs. I put it diagonal on one shelf in the #2 so I could cook it whole. I put a probe in both the flat and point.
I put it in when I went to bed and didn't expect to hear from it until the next morning. In the middle of the night I got alerted that the flat end was already getting close to the target IT. I got up and turned it down the rheostat from 225 to 200 for the rest of the night. When morning came around the flat and point were much closer to parity.
It came out really nice... ate some of it for lunch and sealed up six chunks for the freezer for future meals.
