>...all the courses that are really "great" when played from any tee...
You're on the wrong track. Or, should I say, the wrong tee??
According to GD,
>What does it take to become one of America's 100 Greatest Golf Courses? You've got to impress some very particular people: the Golf Digest Course Rating Panel...
>>> 2. Resistance to Scoring. How difficult, while still being fair, is the course for a scratch player from the back tees?
Apparently, to 'become one of America's 100 Greatest' you only need to be 'difficult' from the BACK TEES for the SCRATCH player.
Other folks from other tees need not apply.
