I think the Flat is harder to cook than the Point. It has less fat and tends to dry out quickly if over cooked. Look at the price. You are paying over $6 for Choice vs $3.29 for Prime. The Choice Flat will need less trimming. I would look for a whole small Prime brisket myself or buy a large one and separate the Flat from the Point and just cook one or the other. You would get a better cut of meat and save $$$ and have meat for two cooks.
I guess it makes sense....will keep an eye out for a small piece whole, maybe a 12lbs so after trimming it becomes an 8lbs...lol
Thanks for the feedback.
