I don't doubt your experience. I was trying make the point that one shouldnt pigeonholed KKW TKD. Kicking is highly emphasized in Kukki Tae Kwon Do ( I'm sure no surprise to anyone) and they have a sophisticated understanding of it. KKW TKDist employ their kicks in a variety of ways and rely on no single manner of execution. For example, fast, snappy kicks meant for speed and precision, the kicking equivalent of a jab, will probably have minimal hip engagement and rotation while a power blow will have full hip engagement and rotation, perhaps similar to what you have seen in Shotokan or TSD schools.The differential isn't lack/occurence of hip power, but with the degree of focus on technique and hip power. I've been to KKW schools and saw VERY minimal hip compared to a Shotokan or TSD school.
