Mmm... but you can be completely "out of structure" and still generate "hardness." The "structure" part provides hardness sure, but I'd say that's only in the beginning. There's something else that provides "hardness", yet is still "flexible." Alternatively it can be soft. At least ime.
It's also what allows the "SJT" (stupid jin tricks), where you can be completely out of structure, yet still generate Jin.
Looking forward to it. By preciseness on point of contact, do you mean the angle of point of contact, pressure you give out etc?
Nice. See, it's possible to have some pretty good discussions without even a single word about anyone else's personality! Good discussion, folks.
