This is some interesting ideas you guys have. I like the use of the "lever" theory taking top, bottom, top & bottom from the front & the rear. That is more material to think about. I'm sure there are many ways to "group" the techniques together. What is your idea on back breaker? In this technique you really don't sweep, or buckle merely pulling the person backwards. In an instance for street self-defense it would be whatever it takes to make it work but in this form you step out slightly off line then around behind the attacker. Once again I'm curious of your thougths.
