Great clips, Brian! Although the style is dissimilar, the 1/4-1/3 speed and power used reminds me of Kung Fu San Soo. This is how we 'spar'. After watching these clips, I believe it's easy to see how effective it is to follow the maxim, Go slow to go fast (one of Jimmy H Woo's favorite sayings). And anyone can see there is pain involved, regardless of the slower pace.
Good stuff! :ultracool
