I play them all, my favorites are Royal St George,....Congressional,....and the Island course in SC.
St. Andrews to me is a challenge, but those greens are like skating rinks, plus the undulations to me are absurd,......but that's only My take!
To each his/her own I suppose! Someday I'd love to see the TPC at Sawgrass become available,...but I'm sure there's a lot more issues gong on here that need to be addressed before more courses become available!
