AMP-RYU
Black Belt
Sticky hands is practiced much more (and likely on a more sophisticated level) within wing chun than goju-ryu karate. I always enjoyed kakie practice in the dojo, and now that I am a teacher I expose even my kyu rank students to it. An understanding of kakie is required before you can really hope to move onto the locking applications within karate.
I teach youn wha style and we work on sticky hands quite often. It is good for hand eye cordination.
