Here is a link to a PP of the week started by Gavin.
http://www.fightingarts.com/ubbthreads/s...=4#Post15778510 Try this one. It has a high reader rating. Gb 20 is one of my favorites. It is the point I used for my first light touch KO. I used it together with a tuite technique (hammer lock) that had uke buckled over making Gb 20 very accessable. (In my school, we're not into a lot of TCM stuff. We go after "Cycle of availability"). The touch was very light, as it should be. I was, after all, hitting someone I liked and who was doing me a favor, in the neck. His legs shot out and he said he felt it all the way down the meridian into the feet. Read the thread. I use Gb 20 for striking, for manipulating a person's posture in grappling. Enjoy.
