btw, I also had some WTF TKD background when I was very young. It was quite a rude awakening when I decided to come to one NCK bu koan
. I joined the bu koan and been practicing NCK since. However, I still keep one kick from TKD; it was my fav kick from TKD. I found it also useful as a combination when the enemy has lost balance, but I dare not to use it as a solo or an opening attack again NCK practicioners; it's a suicide. It is the jumping dwichagi.
