So I watched some Sean Foley instruction videos from Golf Digest Ondemand and in the Power section, one of the topics he covers is how he teaches to hit the driver.
For the driver he teaches
slightly wider stance
let the lead arm hang down comfortably to grap handle, in other words just straight down
put back arm on club, which creates a slight side tilt away from the ball in the upper body ( from ball being forward and wider stance)
so this is your address position now, this creates a weight proportion of 55 weight on back foot and 45 weight lead foot. Sean wants you to stay with this weight proportion for the entire back swing, In other words he doesnt want any extra movement or weight into the backside.
at the top Sean just wants you to come into impact like any other shot, transfering your weight into your front foot and squashing the tomato under your lead foot.
His technique is about creating a higher launch angle but reducing spin. The only difference I see between S&T and Sean with the driver is, S&T still wants you to be at address with 55 front foot and 45 back foot, and with Sean 45 front foot 55 back foot.
Please discuss this, Would like to hear your thoughts on this.
