I learned something as the consensus seems to be that the swale was meant to be kept as fairway. I honestly never realized that. These days sometimes it’s hard to tell the fairway cut from the green surface. My personal preference is for that swale to be green surface and even a portion of the approach in the front of that swale as I think it looks and plays great.
Whew . . . I was sweating it for a minute that you were going to go along with Raynor and Macdonald, and we'd have to agree on something here.
Besides going against whatever Mark says, and sticking with the way Macdonald and Raynor had it, my other reasons for opting not to extend the green:
1. Expanding to the front and the swale is an enormous extra area of green to maintain, especially when the front portion of most Biarritz greens is almost never used for hole locations. [Yale's is an exception, but on most others, they only use the front for ladies' day or for outings.]
2. At a lot of clubs, fairway cut is FIRMER than the greens, so you are more likely to be able to play the tee shot through the swale if the front plateau is fairway.
3. Some of these greens are so big from front to back that having to putt from the front can be a sixty-yard putt, which is an awful golf shot for a lot of people. I personally am very comfortable putting from that distance, but most people would rather have the option to pitch or chip or putt . . . and I'd rather have the option, too.
