So which came first, the locks and armbars or him teaching you?But I know he know it, 'cause he's taught me..
Seeing something and going "HEY, WE HAVE THAT TOO!" is not the same thing as having an established system in place, which is why they keep telling you to go to a jujitsu school to learn it.Every Sifu I have trained with since has let me "use" in free sparring. Every one has shown me the KF equvelant of what I did after class. I have seen people come right out and ask to be taught and herd Sifu tell them that if they want to roll, go find a jujitsu school.
