One thing to remember, is even in the orgs, I have seen what you would consider different styles. I studied at an ATA school under Mike Allemier, who is a tough guy, and high up in Krav as well. He is interested a lot in the self defense. I have also seen ATA guys who are more about the fancy stuff, or the pretty techniques.. sadly these guys do well at point tournaments a lot.. but over all.. if you have a good instructor, the ATA system can work very well. I have been to a WTF school which they just flip flop their kicks and it is all sport.. but I have been and trained at another one which you would say the style was more like kickboxing as it has face punches, and you will see more boxing a lot of the time than you will fancy kicks. So, every school has good and bad. I think people like to look at the worst of other orgs and say that is all they are... this is just not the case. I have also moved in the military and had to go to an MA school which I found to be terrible, but I went in there, and trained hard and still got something out of it... So it is a combo, does the basic foundation, the org have something that can provide a good learning system? I find yes in most orgs. Does the instructor teach the MA in a way which not only works, but works for you and helps acheive your goals? This is one you have to really look at. And 3, do you have the dedication? Do you have what it takes? I can go loose in a tournament, and blame it all on my style, but really.. it was probably a lot to do with me. It is funny, when people come to the reality that they suck, they blame the school or style, when they win, they take the credit.
