I am looking for some advice. I recently did a smoke for my cigar buddies where we did 33 St.Louis cut spare on my 120 gallon reverse flow. I want to do something different for the Super Bowl. My thought is doing 12-15 racks this time and adding 4-6 eight pound shoulders/butts. My questions are: 1. Is that a good substitute or will I be low on meat? 2. Being February in VA, should I expect for 10+ hours for the shoulders? 3. I am staying away from bone-in, as it reduces meat yield and imho increases cook times. Thought?
