I've noticed that when I grapple with (the many, many) people more skilled than I, that I feel very unstable, always over- or under-extended, and basically like a clutz.
On the other hand, when I grapple (the very few) people not as skilled as I am, I feel very solid and stable and pretty much able to move how I want, when I want.
I'm trying to figure out what exactly accounts for this difference. I'm sure timing is a major factor. The better people are moving (even very small, subtle movements) just that much more timely than I am, putting an obstacle in one place, taking the stability out from under me in another. Sensitivity seems to be another, in that they can feel and adjust on the fly both faster and on a smaller scale than I can. Awareness to what's going on is probably another, as is raw processing ability (familiarity allowing them to come to churn through the possibilities faster).
Anyone have any insight into this?
