I agree with both saying about the ground-fighting, most fights go to ground/are over very quickly. I also agree that MMA is very handy for most types of situation and is an all-round good mix of arts to practice.

I've never really taken to Karate or TKD, preffering the more adaptable arts and I agree with the point made about the kicks in TKD, unless you were in a Jet Li or Chan film...might not work so well in a crowded bar.

In Ninjutsu we learned two techniques that you can put on if you're opponant is on the ground, using the shoulder blades to choke them (they're own shoulders blade) and there was another thing...can't remember at the moment.
