Interesting thread. My experience is that the most difficult greens to read are the oldest ones, as they are rife with micro-undulations created over time by mother nature rather than an architect and/or shaper. Because most young greens are designed/shaped/maintained to a perfectely executed plan, an experienced eye can see the plan and putt accordingly. Applebrook and Pacific Dunes in 2001 come to mind.
To me, part of the greatness of Dornoch is the fact that short putts gang aft agley. I once hit my tee shot on the 2nd to 8 feet or so, uphill, and hit a good putt that never threatened the hole. My good friend and playing partner, the great, laconic and sadly late Jim Cunnigham, said:
"Only a long time member of Dornoch like you could have missed that putt."
