I'm pretty new to smoking...this will be my second butt. I'm planning on smoking some pulled pork for a crowd of 30 and was wondering if it's better to get 2 larger (11-13 lb butts) or several smaller ones. The ones they sell at my local big box market are more like shoulder steaks in the 4-4.5 lb range. I would imagine it would take a good deal less time to cook several smaller butts than two big ones. Are there any disadvantages to this? Any help is appreciated. Thanks.
