I moved the thermo to a few more spots, now I get readings of 204 and 206 so it is heading for the foil. Probing feels great in many places.
Slicing and taste test in a few more hours.... we will see how UDS style "low and slow" did over the k-blue.
When I got up at 4:30 for a nature break the temp on the drum was 220, I opened the ball valve to full open from 7/8 or so
this morning at 9am it was holding 225... when I went to bed just after midnight it was at 235.
