Martial Arts folks tend to be over analytical sometimes. People are always arguing what is best and what will and won't work in a given situation. The KISS (Keep It Simple Stupid) method should be applied to martial arts. Don't try to re-invent the wheel. There is nothing can be created, because man has been fighting hand to hand since his beginnings. You can punch, kick, knee, elbow, head butt, grappling, gouge, and throw. That's about it.
