Have a crazy question. I'm about to pull the trigger on a Karubeque C-60 and now looking at various woods. Came across mesquite heartwood ("no bark or sapwood"). Anyone with any experience with this? Any thoughts on whole mesquite vs mesquite heartwood? Any thoughts on adding mesquite at the end of smoking instead of at the beginning (saw a post about starting with hickory/oak and later finishing with mesquite to add layers of flavor). I suspect that this is a matter of taste, but I would appreciate comments from the Keepers of the Blue Smoke!
