Honestly, yeah, find an instructor. If there aren't any near you, then find one who teaches a style you think you might like and arrange to travel periodically. Maybe find out where he's teaching a seminar class or something.
This is actually not an option. The only remotely relevant training related to this nearby, is regular sports fencing, and since my wife did that for several years, I have already established that it is not what I want to learn here. Besides that, I am already committed to BJJ and Hapkido, and cannot fit another regular activity into my schedule. Which is why I'm looking for instructional material in video format, to tickle my interest without a huge commitment, and something I can do when I have available time.
