Hey all. I'm smoking 2, 7 pound butts for a labor day bbq. Gonna do 2 chickens as well. I'm getting scared about the timing. I read threads where the butts take 8 hours, then I read threads where the butts take 20 hours???? I'm doing a simple recipe with a rub and no foil, cooking at 225 to 230. My plan is to start the butts at midnight on sunday...expecting company at 3pm labor day. Should I be good?? Hoping to be done cooking at 1 or 2pm and letting the butts rest till around 3 in a cooler. Does my plan sound solid? Should I start the butts earlier?
