CVV,

The article by Mario McKenna in Meibukan Magazine showing that Tou'on Ryu leg maneuver is really difficult to describe. I met him last summer and he had me work the technique.

It's very different from what I find as a kick, uses the entire body to make it work, and is martinally similar to a heel thrusting kick in Isshinryu's SunNuSu Kata. I really recommend the article, not that you can re-creat the technique from it, but to see how different it is.
