I have recently been thinking about adding a baffle to my UDS because the difference in my grate temps from center to edge have been increasing. When I first started it was only about 15-25 max and now it is about 40 or so consistently. Before I add one, I have a few questions for the UDS guru's. I see that a pizza pan is the most common choice so my questions are... What size pizza pan do you use? Do you use the style with the holes in it? How far above the top of the charcoal basket to you mount it?
