Perhaps I am misinterpreting what Mary and others are saying about the way they move. If so I apologize, but all the talk about hip movement sure pointed in a direction opposite to where I intend to go. Blending and hip-shoulder together while moving also sounded like all-too-common approaches to aiki and martial movement that I don't find too impressive. Again, perhaps there's more and we're all more or less on the same page, but I couldn't gather it from what was written here.
I don't see the movement side of the art as being in any kind of necessary opposition to the internal power / connection side. I really think that taking the basic platform from Daito Ryu and giving it free movement is one of the distinguishing features of the Founder's progression from Daito Ryu, through Aiki Budo, to Aikido. The problem with much post war Aikido was that much of the methodology for the internal side of the art dropped out and what was left was the idea that non-oppositional movement alone was "aiki". Movement Aikido is about avoiding an attack, it isn't "aiki" which is about "joining" not "avoiding".
We do need to focus on developing our own structures properly and understanding how proper connection actually functions. That's the platform. The trick in great Aikido is being able to take that platform and make it movable... at least that's my take on it.
