Serious looking set up! How much of a difference does the Rib-O-Lator make in cooing your ribs compared to putting them on the rack and flipping them half way through? I assume this is to get a more even distribution of heat. The photos of your finished ribs look great - no excess bone protruding or burt ends. Buzz also asks a good question about air leakage and affect on temp inside the WSM.
