Greg Boring,
I'm familiar with both Preakness and Mountain Ridge.
Preakness, along with Suburban and a few other courses, always had fairly fast greens, but, not quite to the speeds maintained by Mountain Ridge.
I agree, it's a process of adaptation.
I think you hit on a key ingredient, SIZE of the greens.
Mountain Ridge's greens are quite large with rare exception, and as such, can accomodate higher speeds.
In fact, on very large greens, such as # 6, # 2, # 3 and # 12, you need high speeds in order to putt from one end of a green to another.
If those greens were moderate to slow, you'd need a wedge.
Members adapt to higher speeds, and once they're attained, they welcome them, provided the greens can accomodate higher speeds and not all greens can.
