swing left, and look like this

[golfbulldog]

I've seen a mat that wanted you to trace a circle with a laser ("F" in geometry). Needless to say, Homer had it right about tracing the straight baseline. 2-J-3 shows us the visual equivalents. Simply placing balls on the ground to cover with the clubhead does not consider the geometric basis of the inclined plane. How would one decide the degree of curvature? There are no degrees of straight lines. Either you're tracing a straight line, or you're not. It's that simple.

How do you monitor tracing a straight line during your swing??

Isn't that why people use visual equivalents.... isn't that what VJ does with his "Putting arc"... the arc is same as placing balls on the ground / arc on a mat surely...?

The best i have got is using a half plane board and keeping left flat /right bent wrists from release to follow through... no reason why you can't use a transparent board and paper underneath and mark on it where your specifc visual equivalents are with a particular club... use the illusions to allow you to perform geometry....

Tracing lines with lasers i find less worthwhile than planeboads... the plane angle can vary so much with lasers... at least in my hands.... whole of he clubshaft lies on flat plane.... keeps same angle better at least during release to follow through...

Chapter 5 is a good place to find the answer. Homer gives us plenty on this subject. HANDS, HANDS, HANDS...

On page 64 in the 7th edition, he gives the alternative (pivot controlled hands). With this procedure, he is less than encouraging.

I love the sentence at the bottom:
"However, if the Clubhead is Monitored directly instead of through the Hands, it is, as always, a chronic disaster."

I guess that sums it up. Thanks Homer.
