So....I decided to use the HOT and FAST cooking method to cook the brisket. I smoked my brisket x 4 hrs at 300F starting at 7:30am the day before. At about 11:30am, Internal temperature was about 140F when I wrapped it in foil and stuck it in the oven at 300F. After about 3 1/2 hours, brisket reached internal temp of 200F and I stuck the brisket into the fridge (actually got someone else to do this as I was away from home and unable to do this). Next day, at 4:30pm, I opened up the foil and slowly reheated the brisket at 250F until it was warm enough to eat. This took about 1 1/2 hours. Brisket turned out fantastic!
