I started with karate, tried aikido for a while. Then I had a big break from training. About a year and a half ago I started karate again from the beginner level. (I'm 24 now.)
About six months ago I started this mixed gongfu style. They don't really care that much about styles or belt rankings. It is a wonderful and realistic system with groundwork and everything included. Full contact sparring. I just hope they some day would explain more about different styles incorporated to the system.
