I'm looking to do 6 slabs of ribs tomorrow on my 18.5" bullet. What would be the best way to fit them on ther? It seems like you can fit up to 4 on a rib rack on each grate, and then rotate them halfway through (swap the grate positions). Or would it be best to try and roll all of them and fit them on the top? I get the swift ribs from costco which I have had good success with before, and they seem to average about 15" in length.
