Tom P
Firstly, let me restate that I think that both PD and BD are GREAT courses--a credit to both their designers and to Mike Keiser. I only started this thread to provoke some discussion, and also because Tom Doak, on another thread, said that he wanted to know how PD compared to Dornoch (and other top courses such as PV, etc.). Vis a vis your questions:
It's been some time since I played RCD, but I don't remember as much blindness as at PD. (BTW, I give Newcastle a solid 3***). To me, all other things being equal, a golf shot where you can see (or at least visualize) what you need to do is "better" than one which requires prior knowledge.
In terms of routing, this is just one of my own personal pet peeves, which I have tried to explain before in discriminating between a "course" and a "collection of golf holes." Both PD and BD suffer from an "embarrasment of riches" in that they had so much land to play with I get the feeling that they went out to find the best holes rather than the best routing. They feel less like a "course" than Dornoch, RCD, Pebble Beach, etc. TOC is very much a "course." Not sure of your point there.
In terms of bunkering, one of the really neat things about PD is sort of "art gallery" of bunkers, both on hte course and in pklaces you would never imagine, such as in hte rouhg and on he walks between tees and greens. They are a tour do force. Strategically, however, they are overused, IMHO.
The top green on #9 is OK, but it is repetitive, in that most of the greens at PD are put on dunes or upslopes requiring a semi-blind up hill shot. The lower #9 green is refreshing in that it offers the only true downhill shot on the course. It should be made permanent, again IMHO.
In terms of RDGC, I did use the qualifer "arguably." My position as a member is hardly non-biased, but I do think that it is, overall, a slightly "better" course than the other 3*** courses I have played, including Pebble, Newcastle, Muirfield, Sandwich, Carnoustie, etc. I have not played Pine Valley, and I'm very much willing to consider that, if and when I do play it, I might well prefer it to Dornoch, given what you and many others have said.
Let's recognize, however, that to compare Dornoch to Pacific Dunes or Pine Valley or Bandon Duens is splitting hairs--but that's what we're all about, isn't it?
Cheers
