It has been written before and better then i could do. What i want to know and see, is why after so much time there are no videos of such of simple thing? There are 1000s of vods of kata and ninjutsu but i can not find just one of ryutai undo. So many are selling for the right price, others have leftt in anger, so at least one of them have let loose one of the "secrets" of this arts. Where are they? I will just say one thing. PR and BW, you made me go after what i want.
