Started about 20 coals in the chimney around 4:20 by 5PM the meat was on. LId temp around 220. Put the temp probe from my E73 on the lower grate. Temps settled in rather quickly and only had to tweek the vents a couple of times. Went to bed the grate was reading220. Woke up and the grate was down to 180. Meatwas at 170. Stirred coals and added some unlit. Within about 45 minutes to and hour temps were up to 230 and holding. I started out with hickory chunks and added some oak in the middle of the cook and towards the end added apple. The smaller butt finishedin 19 hours and the bigger ones were off the WSM in 21. My longest cook to date. Overall, Would do waterless again. Minor problems like bottom grate sticking to the foil over the pan. Temp control was manageable. Also cooked some fatties at the end which turned out FABULOUS!!!
