You have my attention! I'm in as well for some experimentation. I have a Meadow Creek SQ36 that is a beautiful piece of workmanship however it frustrates me terribly because my temperatures are up and down, I'll even get bad yellow billowing smoke at times. I can't seem to get along with it (reminds me of my first wife).
I talked to Jesse from Meadow Creek and he's baffled cause all he hears is how great that model holds a constant 225 degrees???
After reading some of the links here, I'm wondering about a basket with a nice tight stack of wood about 3/4 up then pour on hot briquettes from a charcoal starter on top??? I'm going to try it and let you know!
