KungFu Student,
Shuai Jiao is a great style. Good luck in finding a sifu.

Grappling can be brutal as well. Throwing someone on a hard surface can do a lot of damage. It's even worse if the person doesn't know how to fall. Also, you don't have to "submit" someone, you can break and move on. That's really how you'd do it in a street situation where multiple opponents may be involved. It really depends on the situation. If you are a bouncer in a club, sparring, or competing, to name a few, it's a different story.
