Thanks for chiming and posting good pics / video Mook, I was not familiar with Dai Sau at all. In practice it looks very similar to the outward fook sau movement I was initially taught. I see your point about being able to easily roll to Bong Sau if needed. I don't think the high Tan Sau could roll to Bong Sau without collapsing due since the elbow is already so high.
I only use Tan Sau against straight punches and spinning back- fists mate.
Using it against a hook is just too damn risky in my opinion , the harder you throw a hook against a Dai Sau the more it hurts your arm , I don't feel that against a Tan Sau.
Besides , with a Dai Sau sometimes you get a bonus limb destruction as they accidentally ram their inner forearm into the point of your elbow. :EG:
