The application you mention as being shown to you by YJ is one that I have seen for several other, similar movements. I'm familiar with it and have long used it for demonstration myself though never with this particular transition.
I had thought of it before, but never applied it to this particular movement. I guess I will now.
Yes, smaller circles can, and often do, manifest different energies than larger ones.
Which is one of the reasons why I have learned to expect different applications for the same named postures between the two family styles, one small frame and one large frame, that I practice.
A lot of my students, as well as fellow practitioners, doubt me when I mention that the applications can be quite different in between the same named postures from the two family styles, however once I demonstrate how using a larger circle vs. a smaller circle during an otherwise nearly identical movement can sometimes create an entirely different response in an opponent, their doubt usually goes away pretty quickly.
It's something I am getting more and more familiar with as I progress through my understanding of the art in general.
And then sometimes, as with this movement, I find that the application can be nearly identical using any size circle.
That is what surprises me now, much more often than the other way around.
I guess I'm going to have to compare and contrast each named posture from each of my two forms and look for their similar applications as well as the applications that will work best/better or even only with larger and smaller circles.
It's not like I've got anything better to do!
Seriously though, I don't really have anything better to do.
So I guess I'll get started.
I am teaching a "make up" applications class tonight (most of my Monday night students bailed on me this week, but they had good reasons so I'm holding the make up class) so I'll go ahead and let them work on this.
Why should I do all the work?
