Jim, you mention "Levine". I'm unfamiliar with most books on espada aside from Brinkerhoff/Chanberlain's book. Could you possibly list some good references from your past experiences, like the volume by Levine or others? Always looking to add to my lil' library.
BTW, any luck finding that Adams article? I did several general searches, but didn't come up with anything solid. Part of the problem being, whenever I use 'espada' as a search word, many articles come up in Spanish.
