Back to Mark's original question....
Since I have not played Ridgewood, I can only comment on Five Farms vs. WFE. I would say that the greens at WFE can be, or perhaps often are, more treacherous in terms of cants, internal slopes and green speeds, but I'm not sure that necessarily equates to WFE being better or worse...
I certainly think the natural terrain at Five Farms is much better than WFE, perhaps the bunkering is a bit less penal than at WFE, and I would place Five Farms higher than WFE on the "fun to play" meter, but not by a whole lot...
I have not played Five Farms since the recent tweaking in prep for the Seniors tourney, but I would choose it right now 6 rounds to 4 over Baltusrol-Upper and probably 7 rounds to 3 or 8/2 over Baltusrol-Lower, for example...
Five Farms is, I suspect many on here would agree, likely significantly under-rated on the major ranking lists, but I also suspect that a bit more "national and media" exposure may change that...
