Further on from this would anyone use a Jodan Mawashi Geri (Round kick to the head) or a Tobi Ushiro Mawashi Geri Jodan (Jumping spinning back round kick - made famous by Jean Claude Van Dame) in a fight/street situation
I think someone on here (Fileboy possibly, but don't quote me on that) used a head kick against an attacker before.
There are a few examples of professional MMA fights whereby fighters have won with head kicks. That may not have been the "fight" you had in mind though Ken!:
