WHen I was younger I took Kuk Sool for a number of years. Then I quit because I realized that most of those ancient style martial arts, i.e. kung fu, karate, kuk sool, etc, aren't that useful at all (especially in the MMA world). When they teach you, it seems like for most of those moves to actually work, your attacker would have to be running around with legs spread yelling "kick my in the crotch", and moving abotu 5x slower than a normal person. Also, some of those flying kicks and whatnot are designed for what? Kicking people off horses....useless these days. Also, seeing 8 year old kids beat high degree black belts in kung fu, karate, tae kwon do, and pretty much everything else you can think of with BJJ really does some damage to those arts's reputations. I'm not saying they're not cool or useless to study, but if some hooligan comes at you with a gun, some crazy flying judo chop is going to get you killed, especially when you could bust out some righteous krav maga or muay thai and leave the attacker broken and bloody. I took BJJ for a while and picked up some Muay Thai from a room mate that had taken it for a while. BJJ + MT = unfreakingdefeatable. Had to quit BJJ because it was insanely expensive, unfortunately.
