About the AMNS and the quantity of smoke, one of the great features is being able to double the smoke by lighting both ends. The beauty of is that you are still getting perfect TBS even though the smoke is doubled. The MES chip tray, if you double the wood chips you risk creosote. Once the larger model AMNS is available, it is conceivable that you could light both ends, and the middle thus getting burns going in 4 directions. Or leave a gap in the middle channel and light both ends and only one side of the middle thus getting 3 burns.
I burned Oak for firewood this past year, but a lot of it was still wet or not seasoned enough. I pulled a stump into the garage, and split or sawed pieces into smaller sizes to burn efficiently. I ended up with about 5- 5gal bucket of Oak chainsaw size oak dust. This is perfect for the AMNS, its slightly bigger than the larger pieces in Todd's dust, and thus burn a little different, produces a slightly heavier smoke. I was trying to figure out a way to sift or filter the dust/chips since there is all kinds of sizes from my sweeping. I had an old dip net for minnows or anchovy size fish, it is about 6" in diameter and works real good for sifting a couple of handfuls of oak sawdust at a time.
