I'm a little late, but I'm putting my brisket in brine today for corned beef dinner. A couple changes this year as I'm not doing a whole brisket packer (16-18lbs). Instead I'm doing a 6.5lb brisket flat. I am also using a new Weber Smokefire instead of my trustee Traeger. Everything else seems to cook the same, so I'm sure this will be fine, but I will have to watch cooking temps as sometimes the Weber cooks a little faster than the Traeger did. Also, with just the flat the cook will be a bit more uniform.
