Trevor, Welcome to the forum. Do yourself a favor, get a 6 pak of your favorite, sit in a comfortable chair, serch this site for BRISKET. You may have to get a second 6 pak. There are volumes of info here. Have you ever bought and or cooked a brisket? If not might as well start with finding one that you like. I prefer to buy packers, I don't trim fat except for maybe the really hard fat. I season with a homemade rub that compliments the beef flavor, lately I have been smoking at High Heat , and most important cook till done. Oh and read all the info posted on these forums, and if you still have time there are plenty of other forums to read.
If you have specific questions, there are many here who are willing to give advice, me included.
Have fun!
Mark
