Are there any jodan and/or nito-ryu players on this forum?

If so, I am curious to learn how you got started and how you study. Also, at what level did you change your style?

In my experience, sensei who play jodan and/or nito-ryu are not so common. The only nito-ryu person I can think of is Toda sensei, who used to be a jodan player before he began practicing nito-ryu. There are a couple clips of him in the "Goodies" section of Kendo World.
