I hesitate to jump in to this discussion as I'm a "girl", but here are my thoughts: Most of the flavoring from smoke comes in the first couple hours or so anyway, and if you go beyond that, it can be too strong. Besides, kamado grills are using lump charcoal which has a better flavoring all its own. I would certainly say not to use wet smoking material as it would take a higher heat to keep it smoking, wouldn't it? For me personally, I always cook in a shallow pan, which also allows me to keep the temp. a bit higher than if the meat was directly on the grate, so that helps with the smoke flavoring also. Plus I have the benefit of natural juices flavoring the meat as well, and even tenderizing it. The shallow pan allows for plenty of surface area to get the bark and smoke.
