bas is good but bruce's speed and his jeet kune do is a every efffective systematic deconstuction of an opponent bas's system relies on overwhelming power and toughness bruce in his prime would be hard to hit even hard to inflict damage on it is the power and toughness vs relativly less power but precise enough to put enemies down in quick sucession if the situation called for it bas can do what bruce does but a chance of overkill hence take more time and bas has to cock back to throw a punch taking more time hence more time to move bruce strikes move so fast they make up the lack of body with velocity
