So hastily I went to pick up what I thought was going to be a choice 12 lbs brisket today for an over night cook. I guess I didn't look closely enough b/c when I just opened it, it is actually 2 x ~6lb flats! I have a LBGE but not a tiered rack. I believe they will be touching, what's everyone's thoughts here? Cook it like it was a 12 pounder with them touching? Thanks!
