I studied under Sensei Barathy and Renshi McCaffrey at RAB's back in the early 80s. I was barely 12 years old but it was part of the best time in my life. Im considering getting back into MA (even though im 43 and will be starting over) and my friend who studied under Kyoshi (?) Finnigan, a former ACK instructor, suggested Tai Zen, more strictly a defensive style as opposed to ACK which was more aggresive. What do you guys (and girls) think? Ive researched this method/style and im getting such limited information.
