Erik,
Nice post. As I hinted somewhere, maybe not this thread, when I ask good players about the vaunted "frontal opening" value, its meh. They just club up and hit with more spin to bring it back of the back mound, etc. Most actually seem to just favor hitting the fw if typically narrow tree lined, etc. as the best place to be and the highest percentage chance of getting there. And some prefer the side, as I mentioned, where they have to come over the bunker, because it sets up to curve around it better. Yes, the top distance guys may not, but the shorter hitting and/or grinders still need strategy just to compete. And, that is 2/3 of the tour.
IMHO, average players do need some sort of fw runup to nearly every green. And, their strategy is really two options - aim for the fat middle or shade it over to the pin for a closer putt. And, if they used statistics, they would aim for the fat middle nearly every time (unless it was the last few holes of a match and they were behind.
As I have mentioned before, may PGA Tour pros act as editors more than designers. And one of their most typical comments is "What if I hit it HERE?" Short version, they are looking to avoid any difficult shot for nearly any miss, just like the rest of us, but at a much higher level, LOL. I will say, they look at green contours closely. More than one has told me they don't even consider hazards (well, maybe water) when planning the approach shot as much as green contour. I played a grand opening with one, and was quiet but interested because the green on one hole had a severe cross and slight reverse slope, to see what he would do. He noticed it, and used it in his shot to get close to the pin, even though some of it was blind from the LZ.
