Pat:
If all hazards (bunkers) are in the same places, look entirely different in those same places (extremely man-made vs extremely natural) but play just as challenging regardless, of course it becomes a matter of preference for a particular "style" or "look".
I completely agree with Ran's post above, my preference would be to just make them look as natural as possible if all other things have to be equal. I can certainly understand that others would feel differently than I do, or Ran does, but I can't really understand why.
Let's just look at this subject this way, because it's a subject you constantly bring up. If you asked Jeff Bradley to make you some MacDonald looking fairly man-made bunkers, he could do it just as quickly and just as well as any of MacDonald's shapers and bunker guys do.
But if you asked any of MacDonald's guys to make you the kind of highly natural looking bunkers that Bradley makes for C&C, they likely just could not do it! They don't know how, Pat--or else they've just never done them for some reason noone seems to be aware of. In reality it's because Macdonald's boys do their work with machinery much more than Bradley does and they probably just don't know how to do what Bradley does with natural detail.
Because Bradley can and does make them look so natural a lot of us think of him as an artist. MacDonald's guys are craftsmen, they're machinery operators, not artists, as Mike Cirba has been stressing lately.
We're aware that some people probably don't care or don't even notice the difference and that doesn't make them bad people or anything, just less aware, in my opinion.
So it really isn't much more than that. Some of us admire Bradley, Coore and Crenshaw, Hanse/Kittleman, Wagner, Hine, Doak and his guys and some of the others that do highly natural looking features, because they can do what the other architects and contractors do but they go farther and make their features look natural, and not just the much easier to do man-made look.
We admire those guys that do that natural look because they seem to be the only ones who do it and are probably the only ones who can! For that reason we see those guys as the talented architects (and crews) and the other ones as not so talented--simple as that.
And for restorations, even Merion's, this is why you just are not going to get the same thing if you hire any architect (and contractors and crews). In a nutshell, this is exactly what Ken Bakst is telling you! There is absolutely no doubt about what he's saying--none!
You can give use all the dictates of supervision, oversight, cost analysis, whatever you want but you're never going to get around this simple fact that you just gotta hire the guys that do natural bunkers if that's what you want. In this way all architects, contractors and crews are not interchangeable no matter how much you seem to want to believe they are or can be!
That's just an absolute fact but if you want to know exactly why and how a Jeff Bradley can do what he does and others can't, or don't, I guess with a little thought and effort some of us could explain that to you too.
So the bottom line on things like bunkers is that a guy like Bradley can do what MacDonald's guy's can do anyday, but they can't do what he does! And the fact that what he does is so beautifully natural looking, we just admire the architectural talent a lot more!
But sure, in the context of your post here, all this is just a matter of preference for a style and look!
