I have smoked several butts now, and have always used mustard as a base for the rub. I am doing a 6 butts smoke for Friday and was thinking about trying the rub without a mustard base. For those of you that have done both, which did you prefer? Does anyone use mustard as a base anymore? I've seen allot of people doing it without now, but don't recall what the results were. Since I'm doing 6 butts this go around I was thinking of ways to cut back on the prep time.
