Thanks everyone for yours advice. Thing is that I don't have any choice. In my town there is only TKD ITF and All Styla Karate And I'm practise both . But I wont to know something about this system. Who is author? How it should look like? And thinks like this. BTW I think that peoples look different things in karate. One - efficient, another- japanish culture or art, or something else. Every reason is good to training karate
