I'd love a definition of "quirky," as you see it and are using it here.
My first reaction was that you were using it in a derogatory sense--meaning greens that are unfair, not consistent with good architecture, or just plain bad. My belief is that too many greens being done on recently-built courses fall into this category--they are not good traditional architecture, are border-line silly, and detract from the nature of the course and the non-green rest of the course.
But then when I see the greens you are referencing, I think many are excellent greens--unusual, maybe, but creative, innovative and advancing the art of green building.
For example, I just played Spyglass last weekend, and I love the 4th green. It is perfect for that short par 4--is creative and adds to the hole and the course in a positive way. I would include the 17th green at Pebble Beach in this positive way as well--unusual, but good for the situation.
So, please define for us what you mean by "quirky."
