went around town every meat store and chain store looking for brisket, 1 meat store had them, but biggest size is only 9.7lbs,once I trim it it will probably weigh in at just over 8lbs is that ok for a packer? I am cooking it with 2 7lb butts, and put the brisket on bottom grate fat side down. Cook took 16 hours for Shoulders, and brisket took almost 18 (due to wind) have a 3 sided wind break but didnt do the job until added the final side and covered top, (winds started blowing 25-35) but hey I cant complain they turned out great for only 2nd time. did the overnight method so I was fine time wise
