Dobbersky-san I can only give you my take on sine-wave from my time 20 years ago. As I remember the purpose of the dropping into techniques was to gain power to the technique. It works to some degree.Example: breaking.
My problem with sine-wave is that the time used to drop into a technique makes you slow.It takes too much time. It also looks a little goofy.
I bought into the whole sin-wave thing once, but now it I realize it only has application against another person using sin-wave.
I'm trying not to art bash, but I took ITF TKD through 2nd Dan and I don't use much of it in my new skill set. Alot of it isn't really practical for Self-defense. For sparring it's pretty fun though.
