Good looking smoker. I'd probably cook the big stuff in an aluminum pan to avoid the drippage. Not sure what to do about having the water bowl catching the pucks being above the element...I assume you could add a second hole to allow you to mount the smoke generator at a higher point for when you feel like it (with some sort of block over the unused hole, like the slider for the bottom vent).
Regardless, really good looking, looks like it would hold heat really, really well. Nice job.
