I built a UDS long ago and find it is considerably more difficult to hold temps. I don't think my air control system is very good... I just have 4 holes with pipe for three of them than I can cap and one has a ball valve on it. I just could never control it easily and it was such a hassle to use and clean, I went to a vertical gasser.. made some great cue on that thing, but wanted to return to charcoal. I was hoping the Akorn was the answer.
