Oliver,
I think Lynn Blake's "right forearm pickup" or "magic of the right forearm" is going into your direction. But I'm not really familar there.
Brian-Oliver changed the model from a pure "shoulder turn takeaway" to a takeaway where the hands start rising immediately at the beginning of the backswing. Is there a special term for this in tgm?
Axel
P.S.: Oliver- sorry for the sloppy/unstructured writing which i know you hate. But I don't have the time/energy at the moment to write with more effort. But probaly I could help a little .
