I had it stored in the deep freeze and it took a couple days to thaw. Once fully thawed it got a bath of worcestershire and a good healthy coating of rub. The rub contained onion powder, kosher salt, granulated garlic, Spanish paprika, brown sugar, black & green ground peppercorns, ground cumin and chili powder. I won't bother giving proportions unless someone wants them. It was a good rub, imo.
Here's the brisket going onto the smoker @ just over 300*

This is the brisket just over 2 hours into the cook and already nearing 165 internal. I was just about to foil the meat at this point. Temp pretty steady @ just over 300*

When it hit ~165 I put it into a foil pan and added a premix of apple cider vinegar, water and 4-5T of rub.

I pulled it at ~200 and discovered for the first time that my weber thermo only reads up to 199* and then just flashes, when it's set for beef. I'll have to experiment with it a little more to see if another setting will allow it to go past the 199* mark. I then pulled it from the pan and wrapped it tightly in foil and put into a 250* pre-heated oven, then shut the oven off and left the brisket for 2 hours to cool slowly.
I separated the point and flat then sliced the flat to see what it looked like. The flat was slightly dry (not as dry as the picture makes it look) and was pretty tender, but next time I'll start going by feel when I think it's done. There was a small smoke ring, but considering it was foiled after only a couple hours of smoke I'm surprised there was a ring at all. Next brisket will be done low and slow for comparison; I'm expecting a deeper smoke ring under those conditions. This brisket looks like it could have taken another hour or so, but I'm not disappointed with it at all.

The sauce I made up was a real hit. I was going for a dry garlic sauce, because I love that with beef, so here's what I did.
I pulled 1.5c liquid from bottom of the pan using a turkey baster and mixed in a glass bowl with 1/4c fancy molasses, 1/4c ketchup, 1T granulated garlic, 1tsp cayenne, 1 star anise (ground fresh), s&p to taste.
The sauce turned out perfect without very much fine-tuning at all. I'll definitely make it again. Spooned over the warm brisket, man this was a real treat!

I can't wait to try my next brisket, but I want to make sure I know what I'm doing first, so I'll do a little more reading and research before I try again. Thanks to all for your advice.
