Too bad the editing time is over.
This is the one that I watched quite a few times. I think these two are quite good. They don't blind swing like a lot of the other videos.
I really like their footwork. Also, I think their sticks are thicker and heavier than some of the videos I saw, those all like 6oz skinny stick and they can afford to wack each other non stop and nobody drops. I remember I saw a video the two guys wacking each other from beginning till end, no defense, just keep wacking. I did not see any technique.
