you find that one wood that gives you the results you've been looking for. Been smoking butts a few weeks for upcoming grad party and tried a lot of things. Ran my old standby apple a few times, but just didn't do it for me anymore. Apple/hickory mix was better but still not it. Straight hickory was as many say "too bacony". Yesterday was a toss up between pitmasters blend and oak. Decided on oak. Nothing special out of the gate. First tray went too fast and needed a reload around 9 hours. Decided to add the chip loader and throttle it down a bit and proceeded to do my chores. A few hours later and there it was... Perfect TBS and THE SMELL. That's the one! Happy I found the wood but man these butt smokes take forever. Ran 8lbs hot and fast and still was 15.5hours... Another note to self, do not break a butt down at 1AM or else the whole house will reek of PP for hours.
