Cool vid men, I think I can use this for different attacks too
in wing chun, it's bong sau http://www.fanpop.com/clubs/bruce-le...-yip-man-photo
. in wing chun, that deflection move usually follows with a strike to the center, so that uke has to deal with it and be busy to think of hitting you again and again.
be careful though, that aikido folks tend to follow that deflection in too close to do technique like kotegaeshi. that would put you in the range of the other person elbow and shoulder and other things. i know aikido folks don't attack with elbow and shoulder and the like, but other arts have no such compulsion. taking an elbow or shoulder strike up close isn't pleasant. i got hit by an internal guy with a shoulder strike at zero-inch. he sent me flying a couple of feet. felt like i was hit by a truck.
