My wife has liked my brisket with Jeff's rub both times I made a flat, then I tried a flat with just lots of Salt and pepper. Now she does not want it any other way, the last one made was a full packer and the burnt ends were amazing also along with the salt and pepper sliced flat.
We have all done it!! Go to you tube type in how to cut a brisket or on this forum go to the search box and type it in. good info. You will do well and when you cook one that good and cut it properly they will be all the more proud of your "smokin'"!!
