That seems one heck of a Top 20 - 10 on this side of the pond, 10 on that side.
As I say, I only 'know' these courses from readings and photos, but for me there do seem to be lovely and subtle 'commonalities' (re: 'the whole') that otherwise disparate courses share, eg Ballyneal and Prairie Dunes, Muirfield and Cavendish etc
