Great replies everyone, Thanks...I've got a better understanding now and will attempt to practice with a couple of buddies of mine. I've studied Taekwondo, kickboxing, jujitsu, eskrima, some rare esoteric arts and have taught kickboxing and Taekwondo. Although I feel well versed and happy with the practicallity of my arts, I have a great respect for Wing Chun and truly feel it is one of the more intelligent and ergonomically evolved arts out there. Hence my passion for learning chi sao.
Thanks again for the replys.
