OK I finally decided to give it a try. I'm in the process of doing a hot and fast brisket cook. My plan is 300 degrees for roughly 2 hours. I'm thinking the temp should be around 160 by then. Then into a foil pan with a can of beef consomme until 198-203. Not sure if I will do burnt ends. If so I will cube the point and back onto the pit for a couple of hours.
Will post the results.
My normal cook is 180 for 6-8 hours to get some smoke. Then wrap (foil or butcher), turn up pit to 230, and let it go until 198 or so. My normal cook tends to take around 14 hours on average.
