Thanks Victor, the Rohai was particularly interesting to me as it is not too far from Shotokan Rohai/Meikyo and because it shows how (what I assume were) earlier movements were reinterpreted in the Shotokan version.

I seem to remember seeing a translation of Rohai as something like "vision of a white crane" but I had never made a connection directly with crane kungfu, assuming that it referred to the one legged stance (altered in the Shotokan version), just as our Gankaku (Chinto) refers to this stance not the origin of the kata. Do you know if Rohai was ever practiced in Chinese styles?
