What electrotech said. One thing you can do if you have a very thin end on the flat is turn the thin end under the the rest of the flat. When I do large briskets I shove the brisket together from the point end to the flat end. When you have a tin flat this will make it a little thicker. The top picture is my SMO45 with 3 briskets and bottom is my SMO66 with 3 briskets.
