First, re Sand Hills. I'd rank the approaches like this, in terms of toughest to easiest:
1. Front part of bunker left 7 (toward the tee). That's a LOT approach, all over sand, with about 5 bad things that can happen and one good. The good takes a VERY VERY good shot. Of course I saw Tom Paul pull it off... but he's a great player.
2. Any part of the bunker on 8. Yep, very good possibility to leave it in. But it is a much shorter shot.
3. Shorter bunker shot on 7, closer to the green. Still very tough, still screwuppable, but shorter.
4. Pitches from below right on 7.
5. Pitches into 8. But yes, if the pin is tucked near to the bunker, this moves way up, likely to #1 - at least in terms of getting close. It's never gonna be that tough to just get it on the green. Taking one's medicine and aiming for 30 feet away with a very tough putt becomes the difficult there as well.
I'd have to guess there have been aces made on each hole. But we need Gene for that.
Now... on to WW-PB #15... I have played it but once, and it was quite a few years ago... And I will say it is a great, great golf hole... I just don't recall it as being really reachable, not for me anyway. Make it so, and oh yes we have a very valid contender here. Great call.
