Practice keeping your hands just in front of your fore head...you should be able to watch your hands throughout the turn and cut. If you lose sight of your hands, you are giving uke their posture back.
I believe that is one of my problems...not keeping my hands in front of my forehead...something I will consciously be aware of when I practice from now on.
But Im not really understanding the point about kokyu.
I know Kokyu-ho, and kokynage, but I have a feeling this is referring to something else.
