We may to start calling these drums the Babyback Microwave. Did three slabs today in 4 hours, avg temp, about 220. I also did a brisket, 11lbs in 10 hours.
I am using my spicewine charcoal basket and it fits better now that I pounded down the wings on the edges. I set it on two fire bricks.
For anyone building one, I think I would recommend 3 evenly space 7/8" holes about 2" from the bottom.. Four at the most.
I have 4 1/2" holes in the top of the lid, plus numerous 1/4" holes from misplacing the bolt holes to hold the cooking grid. I was using the eyeball it and drill many times method.
I am sure the UDS would work great with a bbq guru.
