This whipper-snapper has been playing golf longer than many of us have been alive. He's 76 years young. Even though he'd been doing it wrong for 60 years, he changed it in 15 minutes.
I don't know if you can tell it, but in the second set of pics you can actually see lag pressure. The shaft on the left has the clubhead slightly forward of the shaft (loss of lag pressure), where the shaft on the right has the clubhead trailing the shaft (sustained lag pressure). Needless to say, the sound was very different.
