That was me... i ended up not getting any cause of lazy :( for a pork butt (i am assuming 7-9pounds?) Don't do low and slow... do 350 not 225.. you cannot tell the difference and even competition guys do this now, it will drop your cook time by a TON.. Slather in mustard or worstershire (worstershire will stain.. so wear gloves) you won't taste either but they hold the rub on (if you use rub) cover in rub.. Optional to put in the fridge for a few hours to let it penetrate a bit... get it on the smoker for 7-12 hours. Basically til the middle is 175-195 depending how tender you want it, i like to pull mine around 185 as they do keep cooking from risidual heat for awhile.
