I have a 3d - wifi. I've done plenty of ribs, pork butt, and beef ribs. But cooking my first brisket. They had a sale, prime packers for $2.98 lb. That's half price around where I live, so I bought all 3 they had. They have good bend to them, but two of them have really thin flats! They're about 11 lb each, before trimming. Should I leave more fat on the flat to help protect it, since it's so thin? Also, should I separate the point from the flat, since the flat looks like it will cook alot faster? I have 2 temp probes.
