Very nice! Well done. I actually have only been using lump charcoal so far in my kamado, even though I do have a bag of briquettes in the garage. I haven't found a solution with lump charcoal so far on how to get the desired amount of smoking wood burnt in the process. Even when I place my hickory chunks right on top of the spot where the charcoals are lit, I still end up with the hickory chunks largely unburned, and the smokiness of my cooks has been rather mild. I do realise this might be easier to control on a WSM as it burns more fuel and therefore you have better likelihood on catching fire on the smoking wood chunks, too, but anyway, if you come up with any pointers for this with your experiments with lump charcoal, I would be interested to hear.
