"Start the bending of the right forearm right from the start of the take away and work on that with the sequence of the pivot watching in a mirror and you will have a perfect take away in no time."
May I add that it is advisable to start with the right arm in a bent condition right from start-up. The degree of bend of the elbow is determined by what it takes to keep the right forearm on plane with the shaft (sweetspot plane) at address. Mid-body hands...impact hands...no matter... it is a good idea to give the right forearm a relationship with the sweetspot, or at least very close. Unfortunately for us mortals the temporary immortals on the various tours tend to set up with straight right arms, leaving the impressions that that is the way to go about it. Don't forget both arms are straight only at follow through, ergo anything up plane of followthrough has the right arm bent! Magic of the right forearm!
I have just ordered the Alignment DVDs but I feel as if starting with the right arm bent and start takeaway in this fashion I lose my extensor action in left arm. I was told to envisage trying to straigten the right arm on take away to ensure a wide swing arc.
