Citrus of all types are wonderful smoke woods in my experience. If a more delicate (This is not to say less intense, per se) smoke flavor is wanted especially. You've reminded me. I've got five sections of a small trunk (About 5"x5"X5") that I need to split into chunks. Had them about three years since they were cut so I assume they're seasoned by now.
