I think that arts that place large parts of their training on grappling and throwing etc are very effective for use on the street because generally people with little fighting experience on the street will just run at you flailing their arms....but if they were fighting someone from a art such as karate or kung fu who had been training long enough 4 most moves 2 become reflex and the person from the other art grabbed them to apply a lock or attempt a throw i believe the karate practitioner (for example) would be perfectly capable of issueing a strike or kick before the lock/throw was put into use.......while i,m typin i might as well ask wats wit da belts at the edge of each message?
