Just used my MES for the first time on some spares. Started with vent half way open. Not much smoke and not as TBS as I would like, read where you can open side feeder for more air. Will try that next time, also have a AMNS I going to try. No smoke ring and weak smoke flavor. The first 4 hours it looked like a rain forest inside on my window. Never ran out of water and didnt wrap in foil. Opened up vent all the way in last hour seemed like the rain forest stoped, maybe ribs were done then. Ribs were fall off the bone, were moist but not as moist as I thought they would be. Where do you run your vent at?
