Also the Sine Wave has been proven to be introduced by General Choi, to differenciate TKD from Japanese Karate!
This is interesting. Can you please advise who & how it was proven?
Would love to spend 1/2 hour to 1 hour searching through all the forums I am on and speaking to a few ITF instructors. The thing is the Sine Wave ISN'T as old as ITF, it was General Choi's invention and its not apparent in WTF. Also in Choi Kwang Do which is an off-shot of ITF from 1 of General Choi's most senior instructors, the Sine wave isn't there. I have spoken to many ITF instructors who don't see the point in the Sine Wave either!
A man is but the product of his thoughts what he thinks, he becomes.
