I have an 8 pound brisket (after trimming) that I slathered and rubbed last night. I was planning on using the BBGOSM, but some issue's have come up, and I am going to have to use the MES. The brisket is odvioulsy too long for the MES, so should I trim the skinny side down till it fits, or tuck the skinny side under? This is my first Brisket BTW.
