But what about plane shifts - they are common and well-defined within TGM orthodoxy. The plane angle varies but they always keep the same staright plane line.
Isn't the constancy of the same straight plane line the key thing ?
I am keen to understand this properly so please if anyone else can help - I would be most grateful. The point about an "inflexible" inclined plane is OK for zero shift patterns but needs to be further defined for those that shift planes - surely?
I think you're right about the straight plane line being the key thing, as it is one of the 3 imperatives. There's nothing wrong with the concept of the flat inflexible plane, in regards to plane shift. Let's say you have a shift from the elbow plane to the turned shoulder plane on the backswing. You haven't bent the flat inflexible inclined plane; there are, in fact, two: the flat inflexible elbow plane, and the flat inflexible turned shoulder plane. You simply moved from one to another. This is my understanding of the concept.

Bigwill,
I basically agree, and its a minor point, but I prefer to think of one flat inflexible inclined plane, that is basically hinged on the ground (exactly where it is hinged is a little more complex, but I won't go into that!). A plane shift involves moving the whole plane around this hinge. Then when you're shifting planes your not 'between planes', but in the process of 'moving the plane'. Kind of like a door - it can be at a basically limitless number of positions in relation to its hinges (all different 'planes') but it can move from one position to another while continuing to point at it's hinges.

That sounds like the right answer - thanks.
I guess it has to be hinged around the plane line as it runs through the point of contact of the ball?
Is that right - remember we are not scared of complexity if it brings out the truth!

Thanks for your help
I think it probably is the point of contact with the ball - but others may think differently, this is just my intuitive thought (which is why I was a bit concerned about getting into this). If this is right, then it's interesting to think that as the plane shifts, so too does the low point line because of this.
I'd be interested in the thoughts of some of the experts on this (although I admit its just a technical/theoretical question which probably has little impact on how you actually hit the ball!)
