Larry, I was at the game today also.
My notes/thoughts on brisket cooking.
Select the best cut of meat that you can (Superior choice, etc.) or best brisket that can be purchased. Select a brisket with a thick flat with good marbling.
Aged more than 10 days after kill date (which may be noted on the label or ask butcher) is preferable. It can also be aged in your frig if it is still in the original cryo pack.
Aged Beef
Trim off hard fat. Trim fat at point to 1/8 inch for burnt ends or leave fat on.
Optionally use a wet rub as follows:
Mix beef bullion cubes and Worchester sauce.
8 cubes and 1 tabls worchester per brisket.
Then apply your preferred rub.
Get the WSM to 325 or so and add meat and smoke wood, fat down.
Bring meat to 160 to 165 and foil wrap with meat side down (also try fat down and compare results). Adding a little liquid and flavor (ex. red wine, chopped garlic, and onions) is optional.
Begin checking about an hour later for fork tender and every 20 min to half hour thereafter.
When fork tender rest at least one hour.
Separate point and slice flat against the grain. The tenderest meat on the flat should be right under the point. Serve this to those you want to impress the most.
With juice in foil you can use a fat separator to remove the fat and keep the defatted juice "au jus" as a dipping sauce.
Optionally you can slice the point or make burnt ends by putting the point back on the WSM with point up, fat down.
It would be unusual to cook a perfect brisket without a few tries. I'm sure you'll get it down pat after a few cooks. At first, don't sweat the rubs and liquids, focus on just getting down the cooking process then you can experiment with the rubs, etc.
