Ok so I just bought some Farmer John Pork Butts from Smart and Final for only 99cents/lb and they are really nice. They are around 6 pounds each and I was wondering what are the most Pork Butts you've ever cooked in your 18' WSM? The Virtual Weber Bullet says that you can smoke up to four 8 pounders but since these are a little smaller I wonder if I can do six? I would put three on the top grate and thee on the bottom. It might be a tight squeeze but I might be able to pull it off. Your thoughts?
