Skimming through this, I'm surprised no one has said CCC 11 with the old pin location. It's a nightmare to get up the slope of the green and there's that small matter of the water on the right to avoid.
STA 17 is also a dog. It's very long and ridiculously protected with the front bunker and slope of the green while using a long iron.
Oakmont 9 is not a tough pin location, it's a tough green. But like many holes, very much dependent on wind direction and speed.
Jim got it right, Beth 15 with the front pin is actually a birdie hole 60% + of the time for me. The back location can be a snake pit though.Beth 8 with the front right pin is also not much fun when this par 4 is playing like a par 5 in length.
