Wow, with THAT list of 50 you've played that you'd rank above PH#2, you couldn't have suffered buyer's regret.
But, I think those above that speak of subtlety and discovery of playing strategies and features that may only come with time, I guess that makes sense to me.
Also, as an 18HC and a first timer, I assume you played it at a sensible yardage. If played from the tips, probably with rough that is counter to what Ross would have desired to present as his design intent when US Opens where played there, Payne won at -1 and Campbell at E. So, from the tips at toon-a-mint conditions, it can't be a powder puff. I also feel that the acknowledgement of there being 18 fabulous greens seems counterintuitive to any course being seen as underwhelming, flat or not. My local area has a course with great greens, complexes and more or less flatish unremarkable FWs, but I think the approach shots are so much fun that it can't be underwhelming due to general flatness.
But, frank commentary it is from Jim, and well appreciated.
Is there any possibility that there is a dynamic at work that for most anyone that pays $400 day fee, or $275 and very expensive lodging, that no one will actually admit that they didn't care for it? Sort of like all those folks that always say they broke even in Vegas?
