Guys, I have no interest in using the Weber water pan for reasons I already mentioned, and the 14" saucer would sit too high in my ECB pan to allow room for grease drippings from a big cook.
What kind of charcoal are ya'll using? Also, what kind of cooking times/temps are we talking about?
Usually, on an overnight cook, I'm cooking for the next day's supper, so I prefer to cook as close to an avg. temp of 235 as I can. Cooking a little hotter works great, but it shortens my cook time too much, and I don't like to start too late or try to keep the meat hot most of the next day. My last long cook was 16 hrs for two big butts and a brisket, and that's pretty typical of most of my "full cooker 225-250 at the vent" cooks. Most briskets have been just fine, especially choice, and there's no picking out unrendered fat like the other day when I cooked faster and got both butts done in under 11 hours. The long cooks w/ water have just as much moisture, and actually, a more consistant, softer texture. Next time I cook during the day, I'll probably target 250, and foil at 160* to ensure the meat's done in time.
Regardless of the end product though, I can tell from the other day that my cooker's temp would climb well outside of that range if I used only the saucer without a few vent adjustments along the way, at least if using the Stubb's. I guess I could try another bag of the RO chef's select briqs, since they burn a good bit slower. Overnight, the sun wouldn't be a factor, but also, I wonder if a ten inch base under my twelve inch one would be worth a try for the added mass to absorb the heat.
