Not much anymore. Rotator cuff problems limit me nowadays. What was interesting to me in the video was shoulder leading, head across the opponent's body grappling attempt by the bigger guy(similar to the position presented in Guiterrez's Wing Tsun book if I recall correctly)--that was mistake number one. Even so, he managed to lock his hands around the wing chunner's back, but he just picked him up and held him there--mistake number 2. A grappler with even a little skill would have had him on the ground instantly from that position.
I don't really trust this without personal experience, all it means to me right now is your opinion. Its definitely not anything conclusive to me, and all i was asking was if you grappled. I haven't even looked at the video and i am not interested in discussing the whole "if you do this i'll do that" scenario between different arts, its fruitless and seemingly builds walls between arts. Both arts are extermely effective, both can counter each other, both are dependant on the skill level and exposure of the individuals and the how things go on the day. I'm sorry if that comes off at all harsh but i am just wary of entering into this type of conversation as it degenerates every single time.
