I definitely agree with Bob. If you cut the brisket, you'll probably end up with a section of flat and a section with a little flat and just about all the point. The "flat" section might require some special handling depending on how much fat cap was on it.
I don't buy the heavily trimmed brisket flats which are just about all that are available in most NC groceries. Instead, I go out of my way to get a whole packer -- and cook it whole.
