Shaft Weight and Swing Speed
Recently I've seen it talked about that Tiger had switched from a 70g D+ LTD to a 60g, and I thought I heard that it was to help him regain some speed that he felt he had lost. How much would dropping 10g in a driver shaft help with a player's speed? I know there are so many more important variables to getting optimum drives, and these guys have much better passes at the ball than I, but in your experience in fitting/real world, how much swing speed might a player pick up by switching into a 60g-ish over a 70? Not talking about ball speed as the change in weight might change smash factor, but really just wondering about MPH on the club head speed by going lighter?
