Oakmont #9 is a par hole. It isn't a birdie hole, it isn't a bogey hole. it's a par hole. If you hit your second into the bunker, you can stiff the save 90% of the time. Not saying there won't be the occasional birdie or bogey, but not on any kind of regular basis for any but the top players. SA #17 is a par hole too. Same principle - hit close, stiff third, par. BPB#15 is a birdie-bogey hole. It used to be my least favorite, but since I upgraded my driver and am hitting a much higher iron to the green, it has softened a bit. But still, in my opinion the most dangerous green in the game. You can be 4' from the hole and a heartbeat away from a birdie or a three putt.
This is from the front hole placement. Put it on the back and it becomes a par hole as well, as the back tier is harder to get to but a lot more manageable.
