Like I said about Wing Chun, its all theory, and when put to the test, it doesnt work. Remember, I am actually a red sash in the system, under one of Yip Chings teachers, so I know what Im talking about. Not one Wing Chun guy has ever been successful. They have all been beaten very, and I mean VERY, easily.
Their staff fighting is very good though, I will say that. The centerline theory actually does apply to the staff fighting.
