I will add my technique I use in my Extended Party and Fatboy. I fill the basket pretty full, about 10 lb. of charcoal and light an absolute minimum number of briquettes, about 10 in a chimney (yes I use briquettes and this isn't intended to be a discussion on briquettes vs. lump). Place them in a corner away from the fan and set the Guru for 150. I let the temp come up slowly to 150 and stabilize for 5-10 minutes, then I set to 180. Repeat for 210 and then set final temp. That seems to work pretty good for me. I run a 25CFM fan wide open and top vent open about two fingers. The down side is this can take awhile, but I have time at a comp so I take the time needed. I get a good solid overnight cook out of that technique.
