Hi all, I've had a 22.5" WSM for a couple of years now, but I've never done anything besides ribs and poultry on it, so the longest I've had it fired up was about 6 hours. This spring I'm hoping to do at least a couple briskets, and I'm a little concerned about the long cook time. I always see that you should be able to get a WSM to stay at temp for 14-18 hours, but this seems to mostly refer to the 18". I've used Minion Method for my shorter cooks, but after they're done, the coals don't look like they'd go for even 10 hours, let alone 14 or 18. They're pretty burnt out. I usually spread out about 2/3 chimney of hot coals on the unlit coals, is that too many? Anyone had success with long cooks on the 22.5" and is it a lot different from the 18"? I'll probably do some experimenting beforehand so I don't ruin an expensive brisket, but thought I'd try to get as much info as possible first. Thanks.
