Gullane's courses do not display as much variety as the best of the best, but it has always been a place with a very strong identity of its own, which is a great thing to have. A friend of mine used to compare the front nine at High Pointe to Gullane, and I was tickled that he thought so.
There really aren't many other "links on a hill". The original course at St. Patrick's had a fair bit of that, but the hill isn't really in the right direction for the best view or for playing in the wind, as Gullane is. And Gullane uses three sides of the hill pretty well, where St. Patrick's was too abrupt on one side, and too close to the beach on another.
