Well compared with say Mackenzie I guess his greens are certainly less undulating. But all his famous courses have very interesting contours: Portrush, Swinley, Muirfield (probably St Georges Hill, but I haven't played there). St Georges Hill was criticised for having too wild greens when it opened-I've read this in G Illustrated. I always thought Muirfield's greens were among the best and I think this years Open proved it. A varied set with a decent amount of break, even with slowish surfaces.
For very wild greens I think his Eden course has them. And I've posted a picture of the 13th at Tandridge and 9th at Blackmoor which are (were, in Blackmoor's case) definitely wild.
On some courses he appears to throw in one or two wild ones-like the 7th at Beaconsfield, the old 15th at Stoke Poges. With the rest having moderate or subtle contour.
In "Colt and Co", Hawtree mentions some freak greens at Colt's Camberley Heath which were softened before the course opened. The 2nd there, was one that survived. It's a great green according to our friend RT.
The 3rd at Wentworth West was a severe tiered green that embarassed Tom Kite in the World Matchplay. But sadly it was destroyed in the name of fairness!
I believe Hamilton has great green complexes. Not sure how undulating the surfaces are.
