Jeff,
I appreciate and enjoy the spirit of this question; yours is a necessary detail question that contributes to the TOTAL discussion (whatever that is...perhaps, the ever-accruing body of knowledge about GCA)...
Yet I want to take a different tack and make an argument for what is not often stated...that some of the repetitive, "can't-diss-or-not include-PV, NGLA, Shinne, TOC-" favorable group-think (you posit) surveys and reviews that issue here are because those places are worthy of their high praise and there is a line (somewhere) between the ugly, pejorative "group-think" and engaged (or expert) consensus.
Scant access to some of these group-think sacred cows is indeed an issue, (for certainly some account must be given that a player who achieves sparing access is likely to treasure the acquisition of the prize beyond what the golf course may be). Yet my view in those sacred cows I have experienced is that, amazingly, they tend to exceed expectations.
This is true for me with NGLA (3 playings) Shinnecock (2 playings), Yale (12+ playings), Fishers (5-7 playings), Fairfield (5 playings, many loops), Riviera (1 playing), Merion (1 playing).
In all these cases specifically, and to a lesser degree at other places, when I went there to play, I found myself delighted by every vista, apparent strategy, new game question and golf exercise they commanded, somestimes equal to, but mostly in excess of any course/hole I had played previously.
I remember distinctly my first play at National; it was like when Luke sees Yoda command the ship out of the swamp in Empire Strikes Back...that first tee and my glimpses of the course on the way in built a desire to play golf shots liek I never have before. I drove the ball like an absolute animal, hit 13/15 of fairways and shot a fucking 89. But every hole committed itself to memory within me, and I understood the sequential commands of CBM's "amalgamated" design: a draw called for here; permission to hook there; a lofted precision shot that side, a bold blind drive on the other. Skippers, runners, bouncers, roll-outs, dead punches out of the wind, sand sometimes presented as a "change of surface" hazard, not a "hazard of impediment or equivalent penalty;" National, like Yale, like Fishers, just keeps blowing you away with how they present and what they command
And my god, I've never played AGNC, PV, or Pebble but I've been on those courses as a spectator and they look every bit as fun and amazing as those multiple reports, listings, surveys, favorites, and historically laudatory remarks have made them to be.
My point is: Perhaps they are WORTHY to be so-oft repeated and re-listed, because if this player-reporter is actually going to tell you what my favorite courses are--and you really want my honest opinion--those sacred cows would have to comprise my list. I like playing other courses than these a great deal, but if I'm going to try to make rational sense of out of irrational "like" of something, I have to evaluate that my experiences at those on the "list" were/are more fulfillign than rounds at other fine courses.
I'm too biased about the WF courses and Siwanoy (200+ playings, 1000 loops) to not include them in any list...
...its not just group-think is what I'm saying. sometimes a consensus is reached because as good as an under-the-radar/2nd-rated tier course might be, the experiences at many of the sacred cow list are...wonder of wonders...pretty damn awesome.
cheers
