Quick question on smoking one large Boston Butt vs several small ones. My intentions were to buy a large 8 lb bone in butt at the butcher this morning but they only had boneless 2-3 lb butts so I bought three of them. I'm assuming my cook time will be greatly reduced from about 16 hours (1 8lb butt) to about 6 hours since the biggest individual butt is around 3 lbs. Is that correct? Will all three cook about the same time? Thanks!
