I love Osoto!
I'm trying to work on being able to hit it from any grip, anywhere.
For some Osoto tips from the man himself (Yamashita) check out this clinic he did not long ago. (FYI my Coach and 2 teammates were there for it)

In fact click on the posters profile and you have like 6 videos from that clinic.
Coach came back with the stuff he learned and taught it to us. Amazing how simple some stuff is.
