Paul,
Those are interesting questions.
Ones that must be considered in the context of the angles of attack and distances involved.
I find the shot into # 11 more difficult then the score card reads, with but one practical option for reaching it, whereas, on # 14 various options, including mis-hits can do the trick.
I also find recovery to # 11 more difficult because the surrounds at # 14 are more benign.
As to the 9th greens at PV, there's something uncomfortable about the angle of attack into the right side green.
And while it does have some gathering qualities, the right side bunker seems to gather mis-hits or slices quite well.
IF the left green had the trees and shrubs removed from behind it, I think it would be one of the most intimidating approaches in all of golf.
In the old photos you posted, you could see that lack of definition in the approach shot, the inability to gain depth perception vis a vis surrounding features.
In that condition, the left side green would present an extremely difficult approach, as would # 2 and # 17.
The visual and tactical threat presented and the fear of misclubing, on the approach and recovery, to a rear hole location, is significant.
It could be one of the greatest approach shots in golf if it was returned to it's former presentation.
