The serve: the swing path

Just reread your article John. Really very good. Your visualization approach is excellent.

Nothing fascinates me more than swing paths, not just on serves, but all strokes. What if Roger had a different swing path on his forehand? Would it be as good whatever swing path he had chanced upon or chosen? Supposing Roger had adopted a radically different start and dipped the racket down to initiate the stroke like Lendl and Sampras did? What would his forehand be like today if he had.
