Don,
Gladly, although it is in no way a shot at anyone.
As an example, whenever I gave a new associate a chance to route a course, I always instructed to do at least 3 routings in the first hour and as many as possible before lunch. It just seems to be the nature of the beast to get stuck on one "great" idea that any of us have. Usually, they aren't as good as those associates thought. (frankly, few of mine are pure genius either)
The best routing results, in my experience is to have had everyone in the office take the many, quick shot approach to see how many different ideas come out. Brainstorming, if you will. You never know where a good idea may come from or how it might combine with other lesser ideas to be better than it was originally. That seems to be the nature of creativity to me, not coming up with one idea and never considering other alternatives.
The same can be said of any particular feature design, whether greens, tees, or bunkers. Even strategic concepts. As applied to your real world examples, and hinted at in my answer, one biggie in the discussion with the super is always bunker style. I prefer the Mac style cape and bay, but most supers are split between the problems of steep grass bank mowing, and shoveling steep sand banks. (and I have seen those who argue for one, bemoan getting them, but maybe the problems you don't have always seem more manageable than the ones you do).
Short version is, if a super wants flat bunkers, I try to give them to them. What I won't do, is flat bunkers with soft mowable slopes all the way around, because in 30 years, I have never found a way to make those look particularly good. So, we work to some kind of compromise and I look forward to it, as I think it makes each of my courses look a bit different.
My fear is that if I was given total free reign over my last ten courses, each might have come out the same, as I have, using my own criteria, settled on cape and bay years ago. We all get into habits (good and bad) and I don't mind others challenging me to get out of the bad ones, at least! I think we all settle into patterns and need to break them. I think we all have preconceived notions and need them challenged.
And hence, my response. Like I say, I love final control, but also love a lot of input, at least in a general goal setting way. I agree that an owner who takes control of details can be a bit vexing.
