dethhead,
I can't see any mention of tempo, rhythm, breathing or bunkai in your original post...and these are critical parts of yantsu, because there is so little by way of directional change or big sweeping movements. Teh other critical question you have not listed is how you get between the stances...do you move your rigth foot, or left...does it go in front of the other or behind...do you turn clockwise or anti-clockwise. A kata is not a list of stances and punches/kicks/blocks. It is a dynamic, moving "dance" that teaches your body how to respond in kumite or self-defence. I accept that stances and punches are the scaffolding that the rest of it hangs off, but Yantsu is a kata where much of the power comes from appropriate variations in tempo, and good use of visualisation and focus. I hope the video helps you, but, at risk of sounding like a broken record (or DVD), it can't replace a lesson with a real live isntructor. slow down and use those precious ten minutes to make crackling lightening around 3 or 4 bits of brilliance, then the next 10 minutes you can snaffle - another 3 or 4 bits of perfection...and so it goes.
