Someone really versed in Wing Chun is harder to hit than Floyd Mayweather on speed. I got to train a couple of times with a guy that had trained with someone really good - you know how that goes - and I couldn't begin to get past him. He was slippery as an eel. He showed us some basic chi sao that I always thought was cool as hell.

But if you wanna go out and knock someone into next week, both boxing and MT are great places to look. Two of the best striking MAs, IMO.
