BKH, I gave my real life experience as you say you gave yours. I guess we're giving what a scientist might call "anecdotal evidece", and obviously my anecdotes are on the opposite end of the spectrum from yours. Sorry if you were upset by my lighthearted poke at your "sad pattern". Me and Hervé Villechaize thought it was at least a little funny, but he laughs about everything these days.
Fu Pow, I read that article...I assumed Dr. Yang Jwing Ming was only talking about CMA's...and that in his estimation it's alright for a CMA to be "hard as a staff". Note that a staff does bend a bit...and that SD doesn't just consist of hard, straight mostly unflexable motions, but even if it did MY understanding of what he was saying was that there are CMA's like that.
You said, "The point is that there is no geniune art which is hard and inflexible."
So, I suppose I'll disagree with you on that. I may have misread him or you, so please correct me if I'm wrong.
