my son was in a tang su do class for about 4 to 5 years, loved it at first, but in a tournament it was like" lambs to the slaughter". Parents were like wolves egging their of spring to hurt their apponent, it was disgusting to watch.It marred our experience and view, nobody wanted to stop my son getting beaten up by a someone who was so much bigger and stronger than him. I spent a lot of time and money on something that ended up scarring my child. never again
