Does the drag back/through approach require angled hinging? It certainly makes it easy to feel it.

The Lagging Clubhead Takeaway (Unpublished 7th Edition 10-9-A) coupled with its natural counterpart, Drag Loading (10-19-C) is a Swinging procedure. And the Throw-Out Action of Centrifugal Force is most compatible with Horizontal Hinge Action. That said, you are correct in that, since the Leading Left Wrist tends to delay its Start Up Swivel (Left Wrist palm down to the Plane), it tends to promote an Angled Hinge Action (No Roll Feel with the Left Wrist remaining Vertical to the Plane).

If the natural Horizontal Hinge Action of Throw-Out Action (Centrifugal Force) is replaced with the natural Angled Hinge Action of Drive-Out Action (Muscular Thrust), then compensations must be made. A recently published video of TGM GSED Greg McHatton on www.brianmanzella.com at http://www.grumpygolf.com/golf_videos.htm illustrates beautifully this action, together with the required compensations.
