My school teaches traditional Tae Kwon Do, we use the Ch'ang Hon family for forms (Chon-ji to Chong-moo, Kwang-gae to Tong-il) except I noticed that my instructor teaches them slightly diffenrent than the ITF. We are not ITF affiliated. The difference is that the ITF turns counter-clockwise when they are changing direction, our instructors teaches us to turn clockwise, because that is the fastest way to strike your opponent. Does anyone else have an instructor that changes the way one spins in a form form the original pattern? Is this wrong to do?
