I'm love with my 22, you know, better to have the room and not need it, then need the room and not have it.
As far tricks and mods, I like the way they work right out of the box.
I use the minion method to light mine. Fill the charcoal ring with coals and wood chunks and spread a little less than half a chimney of lit coals on top. Put your rig together, keep all the vents open. About 50 degrees from your target temp, shut down two of the three vents and dial it in with the one vent. Pretty easy machine to get the hang of, a couple time and you'll be a pro!
Good luck, and post some pics!
