Kalen, it's one thing when you have an old course that had to add back tees to keep the design current with the modern game (let's face it, most of the members probably still use the original tees) and a MODERN course that is designed that way from the get-go.
I suspect the original querry comes from an observation like you just posted. "Gee, if ANCC has 5, then they must be A) acceptable, B) good design, C) something to emmulate, or D) All of the above. When, in reality, they are E) None of the Above.
