I train in a system that descended from CHA3. My teacher, Master Rich Lewis, currently isn't a member of CHA3, but he trained in CHA3 in Hawaii during his youth (age 13-19) before entering the military service . Later on, but he joined up with his teacher Sam Brown in San Jose, CA. Rich met Prof. Marino Tiwanak when he visited Sam Brown's school before that school eventually broke away from CHA3. Ahhhh, martial arts and politcs.
Anyway, I've checked my arts with some CHA3 instructors that I've met over the last decade, and they say my arts are the older CHA3 arts. My teacher Rich is a traditionalist, and forcefully preserves the system as he learned it.
So, in the end, I don't represent CHA3, but I would like to talk to more people that have trained in that system.
