Very interesting! Thanks for sharing with us all! I know some about kaeishi-waza (reversal technique) but not too much. Perhaps you should start a thread asking everyone to share one reversal and if enough reply to it, we can build are own little library. Reversal are not generally taught and if so, they are taught to extremely advanved. I don't find an aweful lot of sensei with a great deal of experience with reversal.
