I just think it's extremely unrealistic to control a human body from the wrist. At the very least, the elbow has to be immobilized directly.
I think if you enter a control technique at just the wrist, then you better be 100% ready to break the arm if/when you start losing control. Regular practice with the flip, you never really know at what point you would have lost control.
This goes to the small circle versus big circle concepts in hapkido. I think small circle is a neat concept, but doesn't work in practice very well. Small circle also means uke has to turn in less to break the circle.
I have a strong grip, but small hands. Realistically, I have to have both hands on a large boned man's hands and wrists for any kind of control. I have to let go with one hand to establish elbow control and if a big, strong person wants to break loose, then there's not much I can do about it. Fundamentally, from palm to back of the hand, there's really only two grips, three fingers around on flesh of the palm on the thumb side or on the pinky side. If I have a deep enough grip on the flesh, then the primary pushing point is my thumb, not the base of my thumb. That's a huge difference in torque. In other words, instead of ki finger position, I have to lock my thumb out, so its no longer ki finger, it's L finger.
That's my perspective.
But yeah, demo is demo.
