Congratulations on the move up. You're obviously working very hard, and it is paying off. I have a green belt/purple stripe in TKD. I'd like to go back to it one day, but ATM I am taking judo, Shotokan and goshinjitsu karate, so there isn't time.
I'd be interested to know what your forms are.
Thanks! I am currently taking Hwa-Rang TKD. I like it because there is a decent mix of grappling with it which sets it apart from most other TKD forms.
