Superb IMHO you hit the nail right on the head here.
I also think there may be too many people who misunderstand what 'shadowless' means too because I was taught that it isn't so much about 'hiding detectable' signs that you are about to kick, it was all about 'deception' and the simple fact that when I kick, my aim is for the movement to be so fast that it IS shadowless and the same really applies to our hands and weaponry too
That, FME, is pretty difficult
