There tends to be a bias against modern courses. Severe features, in this case sandy green to tee walks, tend to be criticized at modern courses but deemed acceptable at a classic design.
I had an recent exchange with a member of Waverly GC in Portland, who didn't like a couple of the green complexes at Stone Eagle GC in Palm Desert (where I'm a member). It took me a while to process thoughts like these, but I realized a few hours later that Waverly has some brutally steep slopes on the green. Three greens at Waverly (#3, #6 and #11) have a prevailing slope that significantly exceeds any green at Stone Eagle. Modern greens like those at Stone Eagle tend to feature more internal contouring, so the nature of classic greens tends to be a bit different. I decided his opinion was primarily a bias against newer courses, and that older classic courses tend to be accepted unconditionally. It's as if old courses have earned the right to be severe.
Thanks for the subject, so I could post my recent experience.
