I have a MES 30" that I have smoked single butts in before and had good success. I need to smoke 2 at the same time for a work luncheon on Friday. The butts are 7.5 lbs each and too large to fit on the same rack. My question(s) is what racks would you recommend putting the butts on (bottom & middle, middle & top, bottom & top, etc.)? Also, should they both be put center of the rack directly over top of the other one, or each one offset to the opposite side? Any thoughts/opinions you guys could give me would be greatly appreciated.
