well actually i was told that 8-10 years is the norm for the black belt, but then again i bet it all has to do with the teacher. My teacher on the other hand studied at Purdue, and it took him a good time to get a black belt, me other teacher it took im i think 7 years before he got his and he said that he worked his butt off to get there in only 7 years. But we will see, i do enjoy kuk sool, but the art i am going to start taking after kuk sool, rather at the same time as kuk sool is muai tai, very good art, lots of fun. and i have aquestion. In the wrist techniques, i have probles when doing the move holding the wrist in the lock, as in in number two when you go behind the back its pretty easy for them to pull away from me no matter how fast i do it (and this is also my roomate which has no ma background) HELP!
