This may sound obvious to Ted, but just for clarity to the others...

The Arc of Approach Delivery Line is covered by the Clubhead, not Traced (point at). The Straight Plane Line is Traced, and this (superior) procedure should produce identical Clubhead motions as the Arc of Approach procedure. So, by Tracing a straight line we produce a curved motion of the clubhead.

very true
 

Well stated, Tong.

The Finish Swivel Of Arjun Atwal
 

Here is a great view of the Finish Swivel of PGA TOUR player Arjun Atwal as he lets loose on his way to a 64 in yesterday's first round of the U.S. Bank Championship in Milwaukee. Note that the Left Wrist has remained Flat and that the back of the Left Hand and the palm of the Right Hand have Snap-Rolled out of the Follow-Through (the Both Arms Straight position) and into their 'parallel to the Plane' conditions for the Finish (2-G and 4-D-0).

It doesn't get any better than this!

Doc . . . Should this "position" be achieved by a player with a Turned Left Hand grip as well?

Finish Swivel vs #2 Imperative
 

Question: In the Finish swivel don't you lose #2 imperative(clubhead lag pressure point)- leading to clubhead blackout? If so, does this mean that there is a ranking of imperatives?
Any help would be appreciated!

what happened to the pictures
 

Interesting thread. The missing pictures would be beneficial, though.

I am reading all 15 pages of this thread for the first time (as a new forum member) and I was wondering whether an over-swivel action that happens during the followthrough phase (from impact to both arms straight position) of the swing is due to insufficient turning of the upper torso. It is my understanding that the biomechanical action of horizontal hinging operates at the level of the left shoulder socket and left upper arm, and doesn't involve any forearm rotary movements operating below left elbow level. For horizontal hinging to happen without any superimposed swivelling action, I suspect that the body has to turn well through the impact zone, so that the arms are essentially kept in front of the rotating torso. If the body turn movement through the impact zone is sluggish (relative to the speed of the arms moving through the impact zone), then I suspect that there will be an additional non-deliberate rotary movement of the left radius over the left ulna during the followthrough phase of the swing (due to the momentum of the moving club) - and this will cause the clubface to face the ground instead of being parallel to the ground in the followthrough phase of the swing. I don't know if that phenomenon happened in Ben Doyle's posted swing photos, but I suspect that it may happen frequently in many golfers who have a relatively sluggish torso rotation through the impact zone.

Sustaining the lag
 

Watching TT today, I noticed that he uses a high followthrough with a bent right wrist that REQUIRES a full, in tempo pivot before allowing the arms to finish behind the left ear. Lag sustained at all times.

For Swingers, probably the most important video in all the Gallery.

I just read this very interesting thread from long ago. This may be slightly off the original topic but can I ask you a few questions regarding the vertical plane of the left hand cocking and un cocking and the associated club face alignment.

-When hammering in a truly vertical manner does the club face stay vertical and parallel to the left forearm (assuming it was so aligned at the start)?
-When moving this vertical action to the inclined plane does not the club face stay similarly aligned to the back of the left forearm?
-If so then is the face not laying on the plane of the left arm rather than the turned shoulder plane or the hands plane?

I can see how the left hand bends to the shoulder plane as the player approaches top or end but am confused about the club face alignment in regard to the inclined plane at top or during release swivel or finish swivel too for that matter (back on topic)
