Paul,
I partially agree with your premise. 98% of golfers can't come near to hitting it as far as the pros, so why should alter our golf courses.
However, show me a touney where the winning score is 25 to 30 under and I'll show you a course that the pros overpowered and turned the event into a putting contest. From am enjoyment standpoint, those events are crappy to watch. That hurts ratings, bad ratings hurt the game, and on it goes.
I am not a fan of "Tiger Tees" and have no desire to play them, even though I am a good player. But I am starting to think that they are a good thing. I've not yet played Bethpage Black, but maybe they have it right: build a set of black tees that only pros and fools play. The rest of us can play more forward tees and at least have some connection to playing the same course (and similar approach shots) that the pros play.
