Hi BigIr!
We use 2 WSM's and a Weber 22" Kettle. That's it!
We enjoy going to these events and beating all the "big rigs"!
We cook the briskets and pork butts on 1 WSM, then 6 racks of ribs on the other WSM. The Kettle is used for chicken, sausage, beans and dinner on Friday night.
I do admit to getting frustrated every now and again with the WSM and ribs. Most slabs of ribs are between 18-20". Since I prefer to lay mine flat when competing, I always have to scrunch them up to fit them in. Sure would like a 22" version!
