Evan Panatzi of the Kyusho group shows an interesting application.
It is from a Pai Lum form Kin Ken. It was not one of my studies with Ernest Rothrock, and when it surfaced from the Dillman people quite some time ago, I questioned him about the form.
What he told me was the form was nothing special, the fact he switched to Northern Eagle Claw (Faan Tzi Ying Jow Pai) probably makes the point. But value can still exist.
Kata Kin Ken, passed down from the Pai Family Dragon Style, contains a direct attack method on a Target of the Monkey, depicted in the ancient Bubishi. This is also seen in many Karate Kata like Useishi (Gojushiho) and others.
Of course this might be an application for the movement in Kusanku kata where we drop to the floor and strike. In this case the strike would be from behind. I imagine some sort of sentry downing technique if it works.
