hi edshaw
one of the things i noticed most was the the pros start the hip movement when there clubhead is still going back and it put a bend in the club at the start of the down swing, us highter handicap player dont seem to do that. the pros have the bend at the start and it gets bigger as there right elbow pulls into ther right hip. it results in much more bent on the shaft and i think thats where they get so much club head speed, have a look frame by frame at and pro, i have not seen one yet that dont do that, clips of med-higher handicaper dont have this bend or clubhead lag at start of downswing, the bend onlt starts with them about 10/11 oclock in the swing. i watched sandy lyle other week and he only swings to 11 oclock at full swing but the bend he gets on the club as his hips move is huge and he does hit a long 1 iron even now.
