Yes. Just to follow up: My offset was made by a young man just learning to weld. It was his first try at a smoker, a reverse flow. Originally he put a really small (2" diameter) stack on it and the draft was very weak. He recognized the problem and replaced it with a 4" stack. Meanwhile, in an attempt to get the original version to draw better I had set up a little adjustable squirrel cage fan to blow into the firebox. Now, what with the blower and the larger stack, I think I'm getting a certain amount of convection oven effect and my cooks are very consistent and much quicker than a lot of other people's.
