I've just started practicing buki-waza in my local iwama club. I was wondering if anyone knows of any good publications concerning jo and/or bokken suburi?
The best sources that I know of are video tapes of Saito Sensei himself. Some are available on http://www.aiki.com/cat5/cat5frames.html
I have no personal experience with the Crane Senseis' videos/books, but I've heard from sources I trust that they are first rate.
For a quick reference, you might check out the .avi of the testing requirements on http://www.ysaohio.com/
There are some pictures on my site, but I'd hate to offer them up as "instruction material". They are just our club members enjoying their training.
