The reason I hopped on the BJJ train many years ago was because of a few reasons. The first is that I have been practicing striking since '81, and have always been at least decent, if not at times pretty good. Then I sparred a guy who trained in BJJ, and he was able to dismantle me, no contest. Now, I'm not saying it is the end all be all of martial arts, but it has several things going for it. First is, if you become decently skilled at it (lets say one year of training, 3-4 times a week) you would be able to take down and control, or submit, an actual attacker, without harming him. Think about that for a second, as that is pretty dang cool. The reason is because the techniques you need to start in are actually pretty simple, and very effective against someone who is untrained in the defense of said techniques, and when you practice, you practice LIVE. No one steps, no Kata, but nearly full force and speed, with full resistance. The simulates real combat better than probably anything else. If you can find a school that teaches some sort of striking, like Muay Thai, Karate, or even Krav Maga, then you have a well rounded system. By the way, I classify Krav Maga as quite different that Muay Thai or Karate. KM is a self defense art, with a lot of techniques for escaping holds and such, but also includes striking. Muay Thai and Karate, I feel, are more fighting arts, with less emphasis on survival and defense then the ability to deliver a strong punch or kick effectively. I am not saying that one is more effective than the other, but there is a subtle distinction.
