>>A s a martial art I've never rated Judo. It relies on the opponent's wearing a Gi, with thick non-rip lapels for you to grab on. If you tried a judo throw on someone wearing just a cotton shirt you'd end up with just a handful of shirt-front and the opponent standing.

Best body-defence sports (if they can call as sport I'm not sure) are boxing and thai-boxing. These are so easy to learn and so efficient. A friend of mine left Karate at 2. dan, moved thai-box. He says "Karate like children touch game (I don't know this games english name)".
