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.
