This weekend I plan on cooking 2 butts in my WSM. I have always used water in the pan and never had a bad cooking experience. I recently bought 2 clay pot bottoms (12" & 14"). I have heard good things about the clay pot method, but I am nervous to try it with 2 butts on the line. Do the clay pots affect the cooking time? Should I use the 12" or the 14"? I plan on using the top grate only. I'm not sure if I am using bone-in or boneless butts yet. Any suggestions would be appreciated. Thanks.
