Finally got around to using a few slices off of piece of KD walnut. I was impressed at the amount of smoke and how long it provided a smoke for. It wasn't white smoke or a creosote laden smoke but an abundant amount yet light on the nose. I feel it worked well, however due to the issue with my latch falling off in my hand I lost track of this experiment by trying to save my cook from failure. But yah, it appears a go with some minor tweaking. Good candidate for the SS smoke pot, that I will try when my new latch is installed.
