Cooked two briskets and they were great but had one issue. I used a full ring of Kingsford and 20 lit bricks for a Minion method and had all vents wide open. I also used a full pan of hot water. I started it up thinking it would get to 225 within an hour but it would never get over 175. I finally put the meat on at that temp. but it took some 8 hours before it got up to the 225 range. Did I have too much water in the pan?
