Gi, I have in mind the 540 and 720 spinning kicks used in demonstration TKD. I suppose most students never get to this level, but all the TKD demos I have seen involve very high kicks, including some flipping and spinning. I know that's sort of the flashy pinnacle, but I've never seen anything like that in TSD. It has been my experience that TKD also uses very rapid series of less powerful kicks that I haven't found in TSD. Again, I guess it's all experience. Maybe the TKD people I trained with were more sport/demo oriented than what you're familiar with.
