Lynn,
I still ponder if an offset is a better mouse trap in how you can easily clean and tend the firebox?
I'm a firm believer that no matter what type of smoker you have, as long as you can maintain stable temps, it will work just fine. This goes for barrels, bullets, offsets, refrigerators, cement rooms or whatever you use to smoke.
With that said, I
think I would lean towards spending the big $$$s on a Summit Charcoal before I would spend the big $$$s on an offset. The reason is simple, the kettle offers more variety and is more useful to me. I use my kettle at least as much as my WSM, if not more. I would even say that the majority of 'que I do is high heat, so in that sense an offset doesn't make sense, although some have grills in the firebox, that is not a better grill than a kettle. The fact that the Summit Charcoal can do low/slow smoking is intriguing. Would it replace my WSM? I don't know, it's possible. I mean, you can do ribs, brisket, butts on the Summit Charcoal, and it seems a much more convenient way of grilling, and possibly smoking too.
