We have gotten a number of requests to look at the kata, Rohai, and feature applications for it in our Waza Wednesday videos. Now, we don't actually practice Rohai in our style of Shorin-Ryu, but we can look at the kata and see similar movements and sequences in other kata. This is, essentially, what we've done here, with the one-legged high/low hand posture, which we use for both limb and head control.
Thanks for sharing Noah. I always enjoy the commonalities and contrasts we find when we compare similar methods in differing kata.
All the best,
Iain
