Brian : You have done two articles on the Perfect Pivot I think one on your perfect backstroke would be of great interest. Could you describe your backstroke in terms of how you see the arms and hands working in relation to the pivot you have already described? I know you teach hands controlled pivot . Do you see the initial take away move as an arms onl move indipendant of any shoulder and pivot move or do you see the shoulders getting in on the act straight away? Thanks
