Anthony:
Your last question is more for Eric Iverson, who's really the one doing the work at Waialae, but he is wise enough not to spend time here. I don't even know what is on the club's agenda now. I was involved in the greens reconstruction at the [tournament] 6th, 10th, 11th, 17th and 18th, which happened from 2016 to 2018, but I've begged off getting back to Hawaii every February for more work.
[I know, it sounds like "tough duty", but it is hard to combine a commitment like that with my trip to the UK next week, for example.]
This year was the first time the trade winds actually blew like they used to, since we have been working at Waialae. The members have always said if the wind blew normally the pros wouldn't find it nearly so easy. Unfortunately, the winds also brought heavy rain, so the course was very soggy. There is only a little bit of sand there on top of coral -- the fairways are quite close to water table and we hit coral digging the drains for the 18th green, which are very shallow -- so there is not much that can be done drainage-wise in a sustained wet period.
It sounds like they are doing better at mowing the greens tighter to the bunkers which will make things a bit more interesting.
I agree with you about the setup of grandstands at the 17th -- last year they had the same complaint at the 18th, I'm not sure if it was moved back a bit or not. My original idea for the 18th was that, like the 14th at St. Andrews, you'd be better off over the green than short of it, but we had to change our plan because of the grandstand issue. There just isn't much space there between the 18th and the 1st tee and the cart barns to move the grandstands back to allow for that kind of hole, which is also the Tour's way of telling us not to do that. We still tried to get it where there was a run-up shot available because they are hitting long clubs in and it's downwind, whereas if you try to fly it there you have to carry that sharp slope at the front right.
Likewise, there is not a whole lot of space between 17 green and 11, so if they move the grandstands back a lot, they're just going to have to be smaller. I would not be surprised if they liked them tighter, as that's the easiest place to recover from around that green and the players do tend to hedge in that direction.
