The site http://www.aztaekwondo.com/breaks.htm is weird. They appear to be wearing ITF uniforms and the picture on the wall is General Choi Hong Hi, the founder of the ITF. At first I thought the man demonstratging the spear finger break was the General's son, Grandmaster Choi Jung Hwa but its not. Its Grand Master Sun Duk Choi. Plus from watching their form videos they use broken rythem (an older form of sine wave), instead of modern sine wave. I had also thought that Master Nunez was the highest ranking ITF master in Arizona. I would be interested to hear about the affiliation of that school and its history, or to discover that I am completely mistaken in various areas.
