tubercle,
What sort of flavor does pecan wood lend to your chicken? I've heard that pecan is a relatively close approximation to pimento wood, which is the wood Jamaicans use to smoke jerk-style meats. I know a guy who opened a caribbean BBQ just outside of the Twin Cities and he uses pimento wood imported from Jamaica. Aside from finding a direct source (i.e., Jamaican supplier), the only pimento wood that I've found in the U.S. comes as chips, not chunks.
