Bringing up Suarez on a forum often prompts controversy, because of his past legal troubles (if you don't know, do a search, or better several, to get all sides -- don't want to go there here).
Stuff I've read by Suarez makes a lot of sense, even when he's challenging preconceptions. I've also seen a video of his training. It was impressive. He comes across as a lucid, serious minded instructor, highly skilled in his art.
