Jeff,
This thread is so esoteric that it borders on the ridiculous. Outside of this august group, I can't think of a single time when I've heard a user (one who plays golf as opposed to maintains or designs) suggest that bunkers are too perfect. Quite the opposite- and you can poll the owners and managers of the courses you designed- I suspect that one of the most common complaints they get from customers are the poor condition of the bunkers.
As to the courses you note, I haven't played DCC, but most of the rest are known for their conditioning. Yet, not one of them offer perfect conditions for everyday play nor are their bunkers easy to play from for 99.9% of golfers. Those which require caddies typically have better conditions, but they all have some "patrons" who are less than casual in cleaning after themselves. As you probably have heard, a couple of the recently renovated clubs which deepened their bunkers are already considering some changes, not because they are too easy or too perfect, but because some of them members are having difficulty getting out of them, literally.
The Augusta National Syndrome, to the extent that it exists, is probably greatly exaggerated. Except for important competitions, I suspect that the actual number of clubs which truly strive to meet Masters condition (people I know who have played ANGL in the fall and early spring- it is closed late spring and summer- tell of quite a different course than we see on television) is infinitesimal. Those that do, can, by structures that we don't need to consider on this site.
One of the reasons I like your courses so much is your bunkering. Ditto for Jay Morrish. I remember our friend Redanman complaining about a couple bunkers at Cowboys lacking function, serving only as "eye candy". Yet, it is probably one of the most successful CCFAD/$$$$$ daily fee courses in north Texas.
At the other end of the scale, Ridgeview Ranch, Whitestone, Frisco Lakes (Gary Stephenson), and even the now private Lantana (Morrish), all wonderful courses with outstanding bunkering, are suffering from very poor bunker conditions. I suppose that the developers' crystal balls were a bit inaccurate, but more modest bunkering would probably have suited these courses better. Hind sight being 20/20, but then again, would they have gained sufficient following with more mundane features. Drainage, sand quality, and weather are all intertwined in how bunkers perform. I travel throughout much of the country and hope to some day find such conditions where I can start to ponder the perfection of bunkers.
