I'm glad to have indirectly started a topic that generates an unlucky 13 pages of response.
To clarify my initial thoughts on contoured greens, my comments came from Larry Nelson when we were collaborating on our first design (Brookstone in Atlanta) He felt contoured greens took away the advantage of his competitors who were better putters, but less accurate in iron play. In essence, the comparison was between similarly skilled players (ie tour level) with some being better putters and others scoring through accuracy (ie leaving shorter putts).
Given that tour level guys aren't going to three putt that often, the question remains if contoured greens reduce the amount of one putts of the best putteres, while not increasing three putts of other good players.
I think the answer is yes, because a good player who never seems to make a decent putt doesn't necessarily miss by ten feet, he just misses, probably by a faulty stroke, but possibly because of reads. Either way, a good putter who has more trouble reading the contoured greens (or matching reads to speed, etc.) will make less, narrowing the differential in that part of the game. I agree contoured greens (or any other difficulty factor) affect a handicap player 4 times as much as the Tour pro.
