I made probably the best steak of my life today in my MES 30 but I felt like I had to constantly monitor smoke output. I even had a couple small fire in the wood tray because I left the loader out to get more smoke content. I know you can buy a device to load with pellets and it last for several hours. But for random cooks I would prefer to use wood chips I can buy at my local store at the last minute if so desired. Any mods to get better air flow but not catch on fire?
