The green did not look any higher than the dunes running along the adjacent hole, so while the green site might have been raised from the ground below, it did not look out of character for its surroundings.
I found the hole very compelling for the pro's to play. For a hole of a diminutive stature, not being able to see the bottom of the pin from the tee and having no reference point behind the green to gauge distance provided a challenge for the players to hit their yardage. Considering past conversations about how we challenge the best in the world without building longer and longer golf courses, a shot like the one they faced on the 17th seems to be a good strategy.
I was actually concerned watching the hole on Thursday and Friday that it might end up playing too easy, but by weeks end that settled out. As I said before, the scoring distribution ended up pretty close to perfect for what I expect the R&A was looking for.
As for how the members play it. If the open played the hole from ~130 yards, I'd very much hope the members play the hole from 100 or less and the women from ~50 yards. That would provide a more equivalent challenge to them. But my concern is the women play the hole from ~100 yards and find it deeply unfair. So if the hole needs any changes, its most likely to add more short tees for the members play.
