Looks like the load is moving right down your spine and through your hips, which remain loose and adjustable in transferring the load (allowing for kicks, for example). I see where becoming aware of and training the use of the mingmen area comes into play, more clearly with your demo than with most of the taiji push-hands work I've done or seen.
So Tom, if and when I come visit Seattle and ask you to show me... can you explain how a load goes to the hips, yada, yada, but the arms are moving, how those arms happen to be moving if the shoulders aren't moving them? It's going to be interesting to see. I think you missed the whole point, but I'm willing to listen.
