Congrats on the new smoker! You do seem to have a good problem. IMO, I would smoke butts up to 4 of them. FTC and then smoke up to 6 loinbackribs without rack or 4 slabs of spares without rack. The butts will still be hot.
Then when I got tired of doing them like this I would tradein the smoker for a FEC, but then again it might be because they sure look like a lot of FUN.
Enjoy that new smoker of yours!!!!!!!
