I've been running my wsm with an empty water pan and a draft controller for a while now, but the other day I did it and used the lower rack for the first time. I did pork steaks and the side of meat facing the water pan had a pretty significant crust built up, so much that I can't help but think drying might be a concern with long cooks and something on that rack. Do you guys do rotations or something else? I'm considering leaving a more substantial fat cap and cooking fat side down, or throwing a clay saucer back in the pan to help diffuse the heat a little better at the expense of it fighting my controller.
