Jeff:
I have a lot to disagree with in your last post, not sure where to start.
I'll start with the idea that I'll run out of different things to do. I don't see that happening. I intend to keep working with different associates, and utilizing their different natures to add to the course. If I've got a site that doesn't suggest good things on its own, there are a lot of different styles I would love to try a course in someday. I'd like to do a course in the style of Garden City Golf Club, or Pine Valley, or one like Bill Langford or Perry Maxwell -- just like we did for Old Macdonald, not a template of their style, but a combination of their style with my own. [And don't worry, by the time I do my Maxwell homage, Bill Coore and the boys will have gussied up all the clamshells.]
But, as you know, there are business reasons that argue against doing this -- most people who call me liked my previous work, and would be more comfortable with me saying I'll build them a course "just like Pacific Dunes" than "I'm going to do something I've never done before." It takes a special kind of client to be comfortable with the latter, and that limits opportunities to pursue all the different avenues I might otherwise take on.
I think if there is an essence to my style it would be fair to say it's much looser than most other architects' styles. Looser in terms of play -- it allows you to get away with all kinds of bad shots, if you follow them up with a really good one -- but also looser in terms of rules and similarities. I will go with the flow, especially out on the construction site, where I'm likely to have been thinking about the hole for six months with bunkers in certain spots, but build them in entirely different spots when the time comes.
So, for example, I'm not looking to build back-to-back par-3's or par-5's, but I'm more open to the possibility. I was discussing somewhere just recently how I thought my one rule would be to NEVER design back-to-back par-3 holes, because it's so rare to find a good example of them ... but ten minutes after I saw them in Bandon I knew I was going to have to do it. I have only done it twice and do not look forward to doing it again, because it's something you always have to explain and defend, which is why I do not like rules. I'm certain a good number of courses would have been better if their designer had been open to the possibility.
I disagree with you about the routing of two loops of nine holes ... restricting yourself to that configuration on a site eliminates 75% of the potential solutions, and if each of them has an equal chance of being the best one, your math is out the window. Both courses at Stonewall were considerably improved when I gave up on it, and settled for having the course come back to the clubhouse at the 8th green, with a par-3 for the 9th hole [and it was really spooky how the second course worked out the same, when I was not trying to make it do so!].
Now, if the land is featureless [and perhaps "gently rolling" is a synonym for "almost featureless"], then I'd agree with you, the routing doesn't matter much, but the better the land, the more it can matter. Sometimes it works, sometimes it doesn't. I just tallied up my courses to date and here's what I've got for you, by the numbers:
34 courses in all [not counting the nine-hole Aetna Springs, and The Sheep Ranch which has no formal routing].
20 that return at the ninth hole, including High Pointe, Cape Kidnappers, Barnbougle, Ballyneal, and Sebonack.
4 that don't return to the clubhouse / starting point at all [Black Forest, St. Andrews Beach, Old Macdonald, and St. Emilion].
10 that return but not at the 9th hole, including Pacific Dunes, both courses at Stonewall, Stone Eagle, Rock Creek, Streamsong, and Dismal River. [A couple of these would have been impossible to make two loops of nine based on the location of the starting point, because of the balance of areas.]
