I'm starting to prefer the mix of direct and indirect with a diffuser.
This is the same diffuser i use in my UDS and my new jimmy, the holes let some of the direct energy through but not all of it... partial shade When i use this diffuser i'm at just over an hour a pound doing butts. My last butt was a 8 lb in 9 hours and that was in my mini but it's comperable in the UDS
Other times in the UDS i use no diffuser, it just depends on what i'm cooking.
Mini WSM, Jumbo Joe mini WSM aka Jimmy w/ CB & Meat hanging ring, 22.5" kettle w/ CB, BBC (Bird Barrel Cooker) w/007 kit, Big Poppa UDS, gasser grill and Masterbuilt kettle grill.
