Re: The uke/nage paradigm
I think the essence here is the degree/quality of feedback a person receives. I'm no expert by any means, so please forgive any errors on my part, but I think when it comes to moving in general, it doesn't necessarily makes a big difference who is performing technique. I would guess the role of who is expressing the technique or receiving it makes more sense from the standpoint of learning the technique itself though. In other words, we can learn a lot about how to move well/potently without doing the technique itself...particularly if you have enough time to process the experience (relatively slower training), but in learning specific things, we have to be doing those specific things.
