Jud,
Depending on the criteria you use, either it is or it isn't.
I like to strip out view, ambiance, history, reputation, majors held, clubhouse and other such stuff (including how much I enjoy playing the course or just being on the property). I'm looking at golf courses, not golf PLACES. It's not about my FAVORITE - it's about what the architect created and, to a lesser degree, how it's been maintained.
Thus, I only like to consider what's on the ground (which includes water that's in play and the architect's use of the prevailing wind). Nothing else matters (to me, that is).
THEN, I only consider the pure architecture in terms of what I, personally, happen to prefer - much of which I have learned from other people in addition to my own experience.
Based on my personal rating criteria as above, I consider Piping Rock and The Creek to be about as good as Fishers Island. All three of them are excellent and the question of which one I would choose to play every day is a different question and outside the context of my original thread.
Tom Paul:
Touring pro's hit their own shag balls "back in the day"? Try until the late-1970's (at least at Whitemarsh for the IVB Philadelphia Golf Classic). Back when I had time to hang around at those kinds of events, I have filled in for both Hubert Green's and John Miller's caddy during post-round practice sessions on one occasion for each. HG had a whole shag bag full of nearly-new Spalding Dots and John was on the MacGregor staff. In the event that a player hit a shot in the direction of another caddy on the range, the caddies looked out for each other although I have to say that, on both occasions, the grizzled veterans on either side of me were less concerned about that in my case than for their peers.
Golf ball companies weren't manufacturing "branded" range balls in those days and the good pro's wouldn't practice with your standard driving range marshmallows which was all that was available at the time.
Fast forward 30+ years: The last time I was at Pine Valley, I got to hit all the 90 compression Titleists (stamped, "PRACTICE") that I wanted. And that's not a new thing, there.
