Apologies for not replying earlier. I'm not qualified to comment, really, as I am a beginner and only trained in one style (Matayoshi Kobudo). Personally, I found the Okinawan videos most interesting, and always enjoy watching Japanese Koryu!
Choun no kon was the only kata I was familiar with, and I thought it was done nice and crisp. However, I've been taught the 't-stance' move differently...with a higher stance/more power.
Staff is my primary interest...but right now is suffering due to a shoulder injury. Most of the katas I learn are heavily 'right handed'...so now I am trying to work the traditional katas from the left side.
No one has anything to share? No comments, or videos, or anything? Is the staff a primary part of anyone's training?
