@Matthew, I would love it if you could share your recipe for brisket (rub and cooking method).
Rubs -
I sometimes make my own rub, but find it easier to go commercial.
For brisket, this is the best I've used in a long time:

Also good:

Brisket -
For KC Q, I like to separate the flat and the point before cooking, and trim pretty well. That's not always the case for different styles. Sometimes TX brisket, and some BBQ joints, like to simply cook the whole thing, untrimmed, for 14 hrs or more, then slice it thickly all the way through. That's good stuff, there.
(going straight from memory - for home use, go easy on the rub)
Season both pieces and put in the smoker at 225. Around 165 we usually pull the flat and add a little more rub. Some folks like to drizzle a little honey and sprinkle a little brown sugar on it, then wrap in foil and put it back on until it hits 190 or so. Remove it from the foil, let it rest, done. Some folks like the foil, some don't. I use it, it also helps collect juice that can be defatted and poured back on after slicing. Slice it, maybe 1/4" across the grain. Other styles will be thicker or thinner. I think TX BBQ contest rules say the thickness of a #2 pencil. KCBS doesn't specify, but I rarely see the thin slices except at restaurants where they use it for brisket sandwiches.
At 165, do the same with the point, but cook until around 200 to keep breaking down all the collagen in that piece. After that rests, cube it into 1/2" or larger burnt ends.
Wrapping in foil will tend to steam the bark, so removing it from the foil at the end and putting it back on the smoker for a few minutes can help dry the exterior a little bit if that's what you are looking for.
Expect around 50% yield or less on brisket. Buying a 14 pounder looks good, but you'll only get about 7 lb at most after trimming and cooking. Look for prime for the most marbling. And if you really want to spend the bucks:

Might take 8 hrs, +/-. There's lots of room for variations.
