jeff covered this in the 5 day ecourse. but just for a refresher... for a great smoke ring, put the meat on while the pit is still warming up (after the meat hits 140 or so the ring doesn't happen)but also if you load up the pit the temp will drop off fast so what i do (here's pics)is get the pit to 250-300 & load it up(large pit & large cooks) pour some wood chunks to it & it goes bach to around 200-225 grate temp for the first 3 hrs. then i add a chunk or 3 to keep the grate temp 225-250 ( i don't have a probe therm). i don't know it all i just hopes this helps- here's some pics of how mine looks. http://s178.photobucket.com/albums/w...bdaypt2028.jpg
