What I'm looking for is such wonderful design that as you play you immediately forget that the original site was so uninteresting. The architect has done it all. Ideally he has laid on only a light hand and minimal earth moving has been necessary. I am not saying that this is a greater skill or gift than maximising the potential of a really fecund site such as Cypress Point or Royal County Down.
But, having played both Winged Foot courses, it fits the bill. If I were to be a little severe in my judgement I would have to admit that there is a stream/ditch, a lake, and a depression to play over on the 10th West. I don't know how wooded the site was when the courses were constructed. Royal Antwerp is also worth a shout, having been formerly a military training ground, but, again, I don't know how many of the trees which are today a major feature of the course were there when it was built.
As you have pointed out, a course needs only about a 10 foot elevation change to introduce potential blind shots - Hilversum, for example.
