ok here's my opinions on what is written, bear in mind I am not familiar with ikca techniques and am just going by what I read here
1. *headbutt* as the initial move? that's going to get you sent down for assault! In my opinion, entirely inappropriate in a self-defence technique.
2. Knee to the groin - might cause the attacker's head to come back in towards you?!! might also cause the attacker to tighten his grip on you for support?
3. Dropping back with the base (legs) and striking forwards with the arms/hands seems a little uncoordinate - split power etc.
4. Which leg are you kicking with?
Where is 'back-up mass' found in this technique? Where are the other principles you mention to be found?
