I just finished my first hot & fast CAB choice brisket today on the WSM 22 at about 300 degrees. It was an eye-opening experience (thanks, Konrad!). One thing I tried which was a bit of extra work was to separate the point and flat and trim of all the excess fat. These I panned separately. I flipped them over and foiled the pans as each got to 165. In the pans was the au jus that the brisket had created to which I added some water and flavoring liquid. Without having to heat up all that fat must have made an immense difference! The panned point was at 200 after only 3 hours, and the flat was at 185! Half an hour later I checked the flat at 200, and pulled it as well. They rested for an hour in a 170 degree warming oven, swimming in the juices. Doing the pieces separately made it easy to control consistency without it being a compromise. Both had a great smoke ring as well. I saw no issues from having removed all that fat cap and the stuff surrounding the point. It was still very juicy, very tender and had a great flavor. That's going from into the pit to into the stomach in less than 5 hours, including resting.
