Anyway it seems like his clubhead is on a pretty flat plane after transition. (Not flat as in horizontal; Flat as opposed to curved). Something that is probably very good for consistency.
I have a feeling that Stricker would appear to be swinging left if the camera was located in the plane of his clubhead path. There are traces of it even in the current perspective and he seem to hold his wedges pretty well past impact.
I think it is equally interesting to look at the hand path. And perhaps even more interesting - to look at the relationship between the handpath and the clubhead path.
I just watched a sequence of Garcia. That would also be an interesting case. From what I can see his clushaft plane angle changes several times during the down stroke. Garcia's hands are clearly over and then under the plane of the clubhead. Since he is arguebly one of the better ball strikers on tour I have a feeling that his swing can teach us something about the physics and mechanics involved.
I've done the 10-5-E Plane and it's corresponding camera location. The results are surprising. You can't appreciate the geometry until you film one swing with multiple cameras (one under, one on, and one over Plane).
The camera angle of Sergio on the same day and tee is not as good. The camera is under Plane.
