Good info, Tex!  It seems like a lot of folks, in the smoking community, are always looking for the "Nirvana" of wood, when some of the proven "standards" are just what those that eat our Q know - and expect!  I don't look farther than hickory, mesquite, oak, cherry, apple and peach 99.9% of the time.  Maybe I'm limiting my horizons, but I've found people enjoy "familiarity" more than "adventure" when it comes to smoke flavor!
