From the responses I agree as I too think TKD is an excellent art, just sad that the Instructors I have spoken to only see the Tuls/Poomsae/forms as a means to pass the relevant gradings!
Still don't think the wave is a valid technique against any technique
I hear you Dobbersky san. When I look back on my TKD days I wonder what the sine wave was for. It sure doesn't fill the bill it was sold as when I was training in TKD.
