What tbone said, pretty much. I'm using a UDS, sometimes lump charcoal, sometimes briquettes always dry wood chunks. Even in the Weber. I have a Brinkmann Smoke n Pit professional, and when I was using that, it also was lump or briquettes with dry wood chunks. Bigger smokers get fires started with charcoal, then to straight wood, or start with straight wood and the propane starter...YMMV
And of course, the bottom line is the flavor of the final product!
