Hi, all. Second post I did an 11 lb butt last weekend and it turned out wonderful at 1.5 hours per lb and an internal temp of 199 I have invited my work team over this weekend, and I plan to do two butts probably 9 lbs each. I heard you should expect the time to take longer with two in there.... So should I assume 9 lb timing or 18 or somewhere in between? I was smoking around 220.... Could go cooler if it's better. I have time ..... Don't plan to oven cook or wrap other than the one hour rest but I want to make sure that I have it done. Should I start 24 hours in advance and just keep it warm and wrapped longer?
