ok srr guys havent had time to respond. First off you are right every art does hevily depend on set stances and muscle memory. But tkd at least as of what i have seen stresses them more in sparring. Also what i meant by muscle memory in tkd was that as in and art form. tkd is more tournament geard than any other ma system. with it beang tag as you said you devlope you muscles to pull punches and kicks due to hevy tournament sparring. this hevaly takes away froum the selfdence aspect of it. as pulling punches and kicks in a fight can turn out bad. I am by no means saying all tkd students do this. Its just a fact most people have trouble going from light contact to real contact when there body is programed to pull back. as for the agr of and art it has everything to do with how afective it is. Bottom line the older the art the more time it has had to evolve. Just like a chiled. Lets put it like this tkd has had roughly what 60 years to define its self. and tang soo do my art is not much older than that there is no way eather arts have had anuf time. to even start taking out all negitive aspects that art. as oposed to and art thats 300 years old or older. the older arts have one advantage there more evloved and combat tested. thay have had the time to weed out pour tecniques that dont woork or are unpracticul. Now that does not mean thay arte more afective. But thay are mnore evolved and that does give them and advantge in the selfdefince aspect of martial arts. As for are there people in tkd that can take care of busness of coars there are. I am not bashing tkd or its students or instructos. but i will say most not all but most tkd is geard twords sport and not self defince that were the term sport karate comes in that you find in or arround most tkd schools. thats y i would go with something more tradishonal or at least something that trains in a more tradishoil manner with hard sparring and no light contact as you want to know what getting hit fills like. you dont want to be in a fight and just finding out what it means to be realy hit.
