Surprisingly, i am a judo-holic. I also cross train in boxing and tkd/kickboxing as i intend to start MMA when i fisnish my HSC. In my opinion, if you're not training with full contact sparring, your not training to fight, though thats not to say that kata doesn't have its place. Nonetheless, if you don't know what it feels like to punch someone in the face, slam them into the ground and choke them out, and have the same done to yourself then you're never gonna really be ready physically and mentally for the psychological and physiological changes that occur in your body in a combat situation. Fighting is a dirty business, and styles that approach it in a pseudo-religious/spiritual way often lack the training approach necessary to succed in the street and in the cage. Not that overly traditional styles are useless, ultimately training method is much more important than style, as at the end of the day its the fighter that wins the fight, not the style.
