Thomas...despite having never played RND or Brancaster, they were the first courses that popped into my head. The other that I haven't played, that I would nominate, is Pennard.
From the ones that I have seen, National Golf Links of America, more than any other course in that neighborhood. Next would be Pinehurst #2 and Pasatiempo. Courses where the architects lovingly took up residence, speaks to something.
Off the ranked path, I would nominate Astoria in Oregon, Green Lake in NY, Cape Arundel in ME ...
I'll stop. This is difficult.
