I have been to a couple of events that have included the system and I have been disappointed to say the least, what is it that the USAT and the WTF see in this system? It does not work 3/4 of the time. It is a complete failure when it comes to being time efficent and that last thing is you have to really throw an inproper techniques with the roundhouse for it to score, I mean we teach the roundkick but that is going against everything that TKD has been teaching for years.
