Most of those classically trained martial arts guys were raised in Chinese ballet. It's an incredibly strict and bone breaking discipline. They took on other arts from there. I like judo a lot. I've faired decently against 1 and 2 year judo guys on a drunken night or two. I recognize the difference between all the arts and most have a little judo in them. It's about defense and turning your opponents strength against them. More like actual real wrestling. I like kung fu a lot because its about speed, and to achieve speed you need exceptional balance. I like muay thai because it's about recognizing your opponent weakness. It had to be. Thai fighters were always facing larger opponents.
