Mike - cool pictures, thanks.
On your "S" picture, Paul will correct me if I'm wrong, but I think you can also play with shifting the various tees around, i.e. from back to front moving them progressvely to the right (in your picture) so that from the back tees the hole is 'exponetially' harder for the good player (and exponetially easier from the forward tees). That is, from the back tees (as currently indicated in your picture), the hole would not only be longer but would also call for a pronounced draw....with the hole getting progressively shorter and the 'angle' off the tee progressively less pronounced as one moves up.
I'm not sure that's necessary though; even hacks like me sometimes like to play the holes "in the same way" as the better players, i.e. shorter, yes, but stlll asking for the same shots...while hopefully leaving me a little margin for error (but still 'penalized') if I can't pull it off
