Terrific visuals and visual descriptions. I gather your preferred stroke is on the shoulder plane.
What lie angle does your putting arc have?
What is your preferred ball position? Just short of low point?
Do you have any empirical data on the ascending v/s descending debate?
What kind of tempo do you like and why?
Picture #1- There is a lot of discussion concerning the plane angles the putter moves on. The most mis-conceived notion is that during a "shoulder only" motion the putter will move on the shaft plane. This is JUST NOT TRUE. If indeed the shoulders (left shoulder plane angle) are the ONLY moving part during the stroke putter will move in a plane which goes through the THORASIC REGION of the spine.
Moving the putter along a bench with an arm only stroke and then with a shoulder only stroke will both trace a straight plane line, however, the arc of approach and arc of separation will be different. There will be more arc in the arm only stroke than in the shoulder only stroke. The reason is because of the projection of the plane on the ground. The flatter-the more the arc- the more upright the less the arc.
How much does the anatomy of the golfer change the arc?
What stroke and golfer size are the Putting Arc constructed out from?
Are you saying that we're better off with a putter-training device that are more like the bench, if we want a device that people with diffent strokes and/or body-builds can use
Take a look again at the two pictures showing the 'centers' - the left shoulder, and the base of neck/top of spine.
Notice that these are both from a face on perspective, with all lines running parallel (feet, knees, hips, shoulders).
Can you imagine a way in which BOTH of these sets of pictures would be true, depending on your point of view?
This is one of the reasons I personally love the putting setups of Ben Crenshaw and Greg Norman.
They set their feet about 45 degrees 'open' and close together.
They stand fairly tall, arms hanging with the 'shoulder line' square to the intended target. Left arm in line with the shaft.
When you look at them 'face on' (perpendicular to their shoulder line) - you will see one of the two perspectives VJ posted.
When you look at them 'foot on' (perpendicular to their foot line) - you will see the other perspective VJ has posted.
Both views can be seen - depending on your perspective.
Note that this open foot line is beneficial in two important ways. 1) it will help you get your eyes 'on plane' and 2) it will help you feel the right hand 'underhanded' toss motion.
You have the option of using a shoulder powered stroke, or a right arm powered stroke from this setup.
The caveat of course is that special attention must be paid to your shoulder alignment - something that is true for all shots, but made more difficult by the open foot line.

The light bulb just went on with regard to a couple of things, so thank you. I work closely with Geoff Mangum, but it is extremely beneficial to get your(and others) perspective on tilted plane approaches, and the understanding gleaned therein.
Is there one 'dynamic' loft we should be striving for?
Ed,
I'm interested as to how the eyes will be more on plane because of an open stance. I understand that there is some argument with lead eye dominance.

I can only speak for my own experience on the eye alignment, however I find that when I stand in a traditional 'square' alignment, my eyeline tends to tilt out to the right by about 45 degrees. I am 'very' left eye dominant, which as you point out, could be a key reason for this. Also, I think the open alginment helps you see distances better, because you can use more of a 'both eye' view during your routine. Snead putted with a side saddle approach in part because of this benefit (and of course, the 'straight on' stroke you can use). I'll leave the technical bits to those that know more about vision however.

"This involves the Angles of Approach (2-J-3) established by the LEFT-SHOULDER-TO-BALL relationship of the Lever Assemblies."
"If the Ball is struck before Low Point with an upstroke Motion (most obvious with the Putter) disrupting the Clubhead Orbit and the Hinging, then the Ball and the Clubhead Path become circles "exterior" to each other (like two meshing gears)and the line of Compression rotates away and produces a no-spin floater, or Lob Shot. The circle of the ball must be "interior" to the circle of the Clubface orbit and as immoveable as in a spinning centrifuge."
Basing ball positioning off the feet is dangerous, haphazard, and confusing. There is no allowance of a stance which allows for a player to have two seperate low points while using the same stroke. THERE IS NO LOW POINT OF THE FEET.
If it makes us aim better, rock on!!!!! But don't confuse it with low point.
PS- Now we need Lynn to tell us what "circles exterior" to each other are. GO LYNN GO!!!!
