Excluding St. Andrews, here are the courses I played in Scotland on the one
and only trip I've made to Scotland: Carnoustie, Ladybank, Crail, Elie, North Berwick (East and West), Muirfield, Dunbar, Turnberry (Ailsa and Arran), Prestwick and Royal Troon. You know what boys and girls? I submit that, with the exception of one or two greens at Carnoustie, North Berwick East, Muirfield and Prestwick, the greens at these otherwise very fine courses were by and large BLAH! I came at this as I was thinking about Muirfield vs Turnberry, where I concluded that Muirfield's greens were more interesting and "less blah" than Turnberry's. In fact the Muirfield greens are IMO very subtle, which does not necessarily equal "blah," and my view of Muirfield vs Turnberry is admittedly tainted by my opinion that Muirfield is one of the finest routings in the world. Nevertheless, there you have it. BLAH-ness rules some of the finest courses in Scotland.
Just my opinion, which may be tainted by too many single malts during and since, so I could be wrong.
