Tom,
No question in my mind that the lacy edges are attractive. When doing my own bunkers, I try to get them as lacy as possible, figuring they will soften up. Of course, too lacy and the on site superintendent will raise concerns to some degree (or the corporate agronomist who oversees him) and even some players will complain. I do recall playing Sand Hills with a few guys who wondered about what happened to a shot in one of those notches at the bunker lip. Probably screwed was not what they wanted to hear....and they didn't seem to appreciate how the bunkers fit the landscape. We'll write them off as card and pencil guys...
The other thing that makes the Good Doctors bunkers appealing is the proportions. Some bays of the bunkers are 15 feet wide, others 20, or 45, etc. The noses also vary in width, and come not straight down, but at slight angles, and each one is different. The sand heights in each bay is slightly higher or lower, the depths of the capes, slightly different. He or his on site guys had a great touch. It takes a lot of time to get them right.
Where my bunkers have approached the beauty of these beauties, it has been the result of marking, looking, remarking, relooking, and marking again, sort of a modern version of the Wilson Bedsheets, but with spray paint. One marking doesn't cut it, and neither does one opinion, as it always helps to have two of us looking at things. And I can tell you the ones that aren't quite as good because for some reason, the airlines just won't hold the plane for this type of reason
In my opinion, it it these proportions that let them withstand a bit of smoothing, and still make them attractive.
