Sorry, I don't really have anything to add. I think Don's swing is great even though I don't really use it anymore. I still have elements of the PPGS in my swing in that I use a much shorter backswing and reduced turn than I did before going to the PPGS. However, I have abandoned the "skinny horse," outward pressure stance that Don uses to isolate the arms, and I am somewhere between Don and other swing methods in terms of the wrists. I don't keep the wrists as consciously inactive as Don promotes, but I also don't actively c0ck them as some methods teach. I certainly make no attempt to go to parallel in my backswing. That being said, I certainly wouldn't hesitate to go back to a full on PPGS swing, particularly if my back started acting up. It is appreciably easier on the back. And like you say, when I was using the PPGS, I was deadly accurate with my short irons. Without bragging too much, I was played a round with a random guy on a particularly tough course, and on the 18th hole I hit a 150-yard 8-iron to about a foot. It was the fifth short iron I had stuck inside about 3 feet that day. The guy looks over and says "It's like throwing darts." (Some days you eat the bear, and some days the bear eats you.)
