You are going to get a 50/50 answer on this one probably.... Those smokers, like the WSM, are sorta designed to be used with a water pan. If you want easy temperature control at temps between 225-275, I would use the water pan with water. If you want to cook at temps above 275, You will probably need to nix the water.
