I dont have video to work with so Im just going to have to make some assumptions here.What your probably doing is leaning out of your own shots in anticipation of their shot coming in.In other words because of the mental mismatch your worrying about what theyre going to do so much your not concentrating on what your doing.
Think about slipping and driving your shots more then strictly evading,now depending on how big the weight differential is,lets face it,youve got to deliver a dozen for their 1.But your never going to deliver that dozen falling backwards,and eventually theyre going to cut you off anyway
