"However, there is an inverse reaction to technology as well -- as players hit further and further, some believe that greens are the only place where par can really be defended -- that's why Jack Nicklaus' most severe greens are the ones he's built in the last 5-6 years."
Interesting to note that in contrast to what I have been thinking as I become one of those old fart golfers......Jack still may think in terms of tournament golf, although his public statements say he is leaning more towards playability.
Also, I think in terms of what's been built - basically, in the 1990-2006 period, we ALL built courses suited for some kind of tournament that would never come. Currently, I am thinking we have too many tough courses, that slow play, at a time when we are trying to encourage more newbs and speed play. What is the logical design response?
The most interesting thing about this thread is that we tend to lump the "Golden Age" or even the "RTJ era" or "Dye era" into one pot, when all those guys practiced over decades, and probably did have different influences. Most famous is probably Tillies conversion from championship course builder to bunker remover in the depression. Also, recall Pete Dye saying he hasn't used railroad ties in 30 (?) years, but somehow, that image still sticks as one of the key design principles in most folks mind!
Add in the idea that we all want to try different things, and you gotta figure that each architect has a course (or subset period of their career) where greens were wilder. Not sure we can pinpoint if all of us have that phase early, late, in the middle, because the experiences we all have are so different, including external influences, like the economy, mentioned a few times above.
Certainly one influence is the fewer courses you have an opportunity to design, the more you want to put any ideas you might have into any given course, subconsciously thinking you may never get another chance! I can say that almost every new associate I ever had felt the need to overdesign on their first project, which needed some toning down.
