Most of the courses that scored a 10 on the Doak Scale set themselves apart with a group of exceptional short par-4's. To wit:
Shinnecock Hills - 8, 13
National Golf Links - 1, 2, 14, 17
Pine Valley - 2, 8, 17
Merion (East) - 1, 7, 8, 10
Pinehurst (No. 2) - 3, 13
Crystal Downs - 5, 7, 15, 17
Sand Hills - 7, 8
Pacific Dunes - 1, 2, 6, 16
Cypress Point - 8, 9, 13
Royal Melbourne (West) - 3, 10
Royal Dornoch - 1, 5, 15
St. Andrews (Old) - 7, 12, 16, 18
Muirfield - 2, 3, 11
Ballybunion (Old) - 1, 6, 10
As a result I have always looked for similar holes in my own work. A few have been mentioned already, but not 7 & 12 at Ballyneal, or 4, 6 & 15 at Dismal River (Red).
