You fellows have forgotten more about the golf swing than I will ever know, but I've come to the following conclusion with regard to the "swing":
The golf swing is not a swing at all. When I think of the phrase "golf swing" I think of an arm generated activity. And, that's been my problem. Working hard and experimenting over the past few weeks I've concluded that the "golf swing" is a pivot generated activity with the arms, hands and club just going along for the ride.
I am currently working on making a big shoulder turn, "setting" myself at the top, "driving" my pivot, and allowing nature to take its course. It's a work in progress to be sure, but when done correctly the results are impressive. There is no lag to hold, there is no conscious effort to drive the right elbow into the side, there is no need to hit down on the ball. It all just...happens. The pivot makes it so.
The "golf swing" isn't a swing at all. The "swing" is just the reaction to a well executed pivot. Without the pivot there is no swing.
