going to try a chuck roast this friday for the ncaa tourney as im having some buddies over and nothing better than some good beef and beer. i already plan t smoke between 225 and 250, wrap at 165 and take to 205-210 for pulling . however, i have read that some individuals put a foil pan underneath to catch the dripings. im using an MES and wonder if this wil affect my smoking temps and what everyone elses thoughts were. thanks!
