Ditto on the other's advice. The only thing I will add is that with the 22" and Kingsford I can't go 7 hours without at least stirring the coals and usually adding a little. The Kingsford burns up fast and will smother itself in ashes if not stirred. I usually start with kingsford and then add some wicked good lump if I am going to try to get some sleep.
I like to keep it between 200 and 225. </div></BLOCKQUOTE>
Sounds like someone needs to find some STUBBS, and it seems like Lowes is about the ony place that has them. (No, I don't work for either.) Seriously, I bet any Kingsford fan would be pleasantly surprised with how long the Stubbs briqs will last and how they don't need stirring. Lots more wood char and lots less binders is a REALLY GOOD THING, so don't think for a second that Kingsford is the longest lasting, most reliable briquette available.
Regarding cooking sub 225*, I'm always curious about cooking times and how folks measure temp in the wsm before I assume they mean actual grate temperature. I've cooked -225* on other cookers and know that pork butts and such take a LONG time to get done when cooked that slow, as much as 2 hrs/lb., and I've yet to see the advantage, (no matter how much I read my Great American Barbecue & Grilling Manual by "Smoky" Hale.
)
On a related issue though, this is my observations with the'09+ wsm gauges: I'm on my third one, and they all seem to eventually start reading a little (or a lot) lower than 212* in boiling water. Furthermore, I can get 250* measuring at the vent with my Maverick probe or another calibrated therm, but at the same time, the OE gauge (even if still testing to be fairly accurate) won't start off at no more than 220* or so, especially in the first half of the cook or so.
Regarding my own cooking times and temps, I have a heck of a time measuring temp on a full grate in my little wsm, so I don't even try that anymore. On my last overnighter, I cooked two butts and a brisket to tender in 12 HOURS, targeting 250* AT THE DOME VENT, roughly 1.5 hr/lb for the two butts and 1hr/lb for the brisket. In my experience with different cookers and also from what I've read, that's pretty typical cooking times for 250*, so measuring the temp in the exhaust vent (in the stream of circulation) seems to get me closest to the actual average cooking temp.
