Not to sidetrack this, but I find it interesting: Tom D and other architects and many of us here have often said that golf architecture is "subjective". And yet, over the decades architects have continually gone back to their designs to tinker/revise: as Tom mentions, in different ways and for different reasons, Tillighast did and Ross did and you could say that so did Old Tom; and today, of course, you have Mr Nicklaus going back and re-working some holes, and you have Pete Dye doing the same, and (famously) you have C&C tinkering with the 14th at Bandon Trails. Now, yes, there are many reasons for architects re-visiting their work, and yet one reason at least (and at least some of the time) is that they go back to make a hole/course better. And, when Tom is doing renovations or restorations on classic courses, again, the client and the golfing public is expecting only one thing, i.e. that the course, when Tom's work is done, will be better, and widely recognized as better. Yes, the collective or consensus opinion doesn't mean it is an objective fact; but, do we really believe that what all these architects are doing to these courses in trying to improve them is merely a subjective exercise?
