yea thats probably it, the time invested? i'm going to rework it to a more home cook thing. i'm sure we all mostly agree that smoking (putting on the bark, infusing smoke flavor) is done by the 6hr mark, you can't shove more smoke in there once the bark is formed. so usually i just butcher wrap and put it in the oven for 12hrs on 220. then turn off the oven and let it rest in there for another hour or 2.
w/ the goldies i kept in the smoker for 20hrs, but it was annoying babying the fire for that long, then foil wrapping it and putting it in the oven for 110.
next time i'll smoke for 6, transfer it to a 220 oven unwrapped for another 12 then wrap towards the end.
