Just put on some ribs to cook for the day so I've got some time to relax and think BBQ. Here's a question. Once or twice a year I go out on the web and look at high-end pits, the kind with the offset fireboxes made by David Klose, Pitts and Spitts, etc. Even the small ones for "family" use are $1500-$2200, and they look beautiful; most of my cookbooks swear by them. But as I was ogling them recently I realized I had no idea why (or if) they are better than a WSM. Obviously the big ones cook more stuff and are designed for competition, but the smaller ones are only marginally bigger than a weber. There must be some advantage or people wouldn't pay 10x the weber. So what is it? Is rectangular better? Is the heat/smoke distribution better without the water pan? Is it better to cook with wood than charcoal? Is it easier to lift the lid without setting off major changes in the fire? I know there are cheap versions of this kind of smoker that sell for less than the weber; but i'm interested in the high-end stuff. (And I'm not putting down the wsm at all, not looking for reasons that the wsm is the best smoker in the world. I love my subaru to the end of the world but would admit that a volvo or audi is a better car...)
