Kevin, Pat, Tom,
I think the whole Classical/Modern distinction is flawed.
Private/Public is a far better distinction although not ideal. THe best distiction IMO would be "one play"/"repeat play".
The real change in architecture around 1960ish was, not the change in construction equipment but the trend away from private clubs towards building courses that were only designied to be played by players a limited number of times (resort courses and high end public courses).
These courses lacked subtle strategy, blind shots, intricate green complexes and angles. THese courses had bold obvious strategies that started at the tee rather than the green -island fairways, risk reward par 5s, etc, - that the player playing the course for the first (and possibly only) time could understand and enjoy. These courses also had a huge advantage over most classical courses when it came to memorability. Water carries, dramatic scenery.
In recent years, the trend has gone somewhat back towards more subtle members courses and it seems somewhat silly, if a distinction is to be made somewhere, to compare these course to the public courses of the latter half of the 20th century rather than the similar member courses of the early 20th century which they are designed to compete with in the market.
I would like to see a magasine release rakings based on two categories:
-one play (eg, if you had one round of golf left in the world, where would you want to play)
-repeat play (eg, if you had to play a course every day for the rest of your life, where would it be)
Of course there would be some overlapping in the rankings, but it would do a far better job of comparing apples with apples.
Failing that, I think that Public/Private is a far better distinction because the architect was generally designing for the same type of play.
