One question. why the diffuser over the coals? One beauty of the UDS is that is provides different methods of cooking, including convection and radiant heat. I also have bolts for a third rack in my UDS, just over the coals, and I can stick a tile or different sized pizza pans on the bottom one so it can be used as a diffuser if I need to limit the radiant heat for the longer cooks.
My main objective in that little guy was trying to a very even temp in as large an area as possible when needed. When I do bacon, sausage, jerky etc, I need as much room as possible, so I plan on using all 3 grates for that. It's all removable via 1/2 ss nuts and lock washers, so I figured if I don't like it, away it goes. I don't plan on using this for ribs, butts, briskets etc unless I'm cooking 3 grates worth. Most the time I'll probably just use the low grate for diffusion if I even use diffusion. Looking forward to trying a brisket diffusion free tomorrow, see what that's like.
Fwiw, early tests show pretty consistent temps throughout. I may add a few small holes and tinker some more, as the outside was about 30 degrees hotter than the middle on the lower rack, but coming from a COS, I'm pretty happy with only a 30 degree variant.
