By the way, I'm not only talking about not buckling the torso, I'm talking about all the joints (shoulders, elbows, etc.).
Ok, so you say that by being centered you mean you hold the body by structure so that it won't buckle. I'd kind of expect that the structure would be fairly rigid, so you'd be easily toppled, so you wouldn't stick to the ground very well.
But you say you can be non-buckling (centered as you call it) and grounded in any position. To me that sounds a lot like "C". Are you saying you learned to do it in two years? And are you saying it was actually just a couple of tricks and athletic training?
Wouldn't the first point be more along the lines of bracing, even if using structure, and thus a no no IS wise?
