Tom Paul;
Thanks and glad you enjoyed the thread.
I agree with you that there was a historical separation in design trends after the Golden Age, which itself seemed to be driven by technical changes in the game and the need to further "test" the best players. RTJ's changes at Oakland Hills are the best known example.
However, I think two things have happened in recent years and are happening as we speak. First, there has been this sort of "mini-renaissance", or "neo-classicism" school that has sprung up for any number of reactionary and pragmatic reasons.
Secondly, the modernistic trend of building increasingly longer, more visually dramatic, and more difficult golf courses has accelerated at the same time. We don't even blink anymore when told that the newest course plays 7,700 yards from the tips, has 8 water holes, signature waterfalls, and other "challenging" features. Slopes of 140+ have become de rigeur and almost a cliche.
So, if there has been a "split in architecture" for the past 50 years, I think that what's happened in recent years is that classic trends have been "reborn" in one school (the modern school really dominated for a LONG time until Pete Dye), and course difficulty and visual dramatics have accelerated in the other. Interestingly, Dye sort of spanned the gap between both schools of thought, although his most recent work seems to have more in common with the dramatic modernists.
You seem to believe that one side or the other won't "win", but will peacefully coexist and although I hope you're correct, I think another factor is at play here that wasn't so much until the past 20 years, or so.
Television.
The ubiquity of television, and televised golf contests, has the power to create a globally shared "perception" of what is a great golf course. It also has the power to homogenize that perception, to a great degree.
Patrick asks on another thread whether "vacations" have ruined design by introducing water features, visual dramatics at the expense of sound strategies, etc., and he wonders whether the fact that "everyone" (not only the rich and discerning) can afford vacations has "dumbed down" design.
I'm not sure that everyone who plays golf can actually afford to winter in Florida or Arizona and be exposed to those tracks, but most everyone who plays owns a television and sees what a "GREAT" course looks like each week on everything from Doral to LaCosta, to the latest $80 million CCFAD sponsoring the Wendy's 8-Tour Challenge Skins Match.
As JC_Mertz mentioned;
"I believe the answer to your question was revealed long ago by the cliche: "the emperor's new clothes"! There is a distinct lack of consciousness in the world, let alone the world of golf, and this scarcity accounts for the other Great Truth: "the blind leading the blind". Just because a guy has his grill on TV and spews forth dribble does not make him right. But you know about the masses...if it's on TV it must be true!"
That mass perception starts to seep into the public consciousness and not only affects new design, but also accounts for how people view their own course. Do we wonder why so many classic courses are "modernized", often simply for the sake of someone's idea of "better aesthetics" and "fairness". Do we wonder why bunkers and other hazards are "dumbed down" for the sake of fairness and white, sandy, uniform attractiveness? Do we wonder why maintenance crews are run ragged to keep things green and soft, or why green speeds that verge on insanity are demanded by memberships?"
There used to be a time when a golfer might play his home course, a few others in his region, and maybe 1 or 2 on his annual vacation. That was the extent of his "shared experience" and largely created his perceptions and ideas on what a golf course should be. Here and there you'd have the Macdonald's or Tillinghasts or a few others with the wherewithal and interests and time to travel and gain and share a wider understanding, but for most learning and playing the game, they were "beholden" to those experts to tell them and show them what was good.
Now, everyone's an expert! Even me.
Mass appeal has always tended to have a "least common denominator" factor associated with its popularity, and as much as we might want to think that we can exist in some type of splendid isolationism, I don't see it happening.
It's a world market that we're in, and we'd best try to compete with our ideas as passionately, intelligently, and eloquently as we can because someone's viewpoint is going to become the predominant mass perception of what constitutes great archictecture over time and those ideas are going to drive not only new course design but further and more dramatic changes to existing classic courses, as well, I believe.
