It's not Hendrick knowledge of WC that gets people rolling their eyes dude.
It's his " I am right, you are wrong" approach and his insistence that anything other than HIS way of doing WC is NOT the correct way.
( I think that sums it up).
*turns on his snake engine and drives away*
Psalms 144:1
Praise be my Lord my Rock,
He trains my hands for war, my fingers for battle !
IMHO,
This above type of stuffs is over simplified.
Without the linking delinking, loading releasing, angling shifting, these degree of freedom, one will not have alternative but a head on collision. And the outcome is predictable.
WCK chi sao is a big part playing and mastering the six degree of freedom at the boundary of the contact.
Thus, IMHO, WCK inch power is the ability to handle these six within an inch of pre - post contact and within a second of the pre-post contact. It is not those inch punch demo, but the ability to have alternative and power generation in this situation.
That is the close range sticking uniqueness of WCK.
Just my five cents.
