Regarding Kingsley:
No doubt it is a very hilly site, but so is Crystal Downs, which has wonderful angles of attack. My little critique is that there is room for wider fairways on the 7th, 8th, and 11th. And the trees down the right on the 15th ruin the possibility of pulling off a great shot from a poor angle
Maybe I'm misunderstanding you, but if you're talking about Kingsley, the 8th fairway is 60-70 yards wide on a short par four where most players are hitting 3-wood or hybrid, and 11 is a par three. The fairway on 7 pinches if you're hitting driver, but it's a three shot hole with ample room to hit the fairway off the tee, and the layup areas where one sets up an approach is effectively 50 yards wide with a couple of very different ways to play it. Meanwhile, while I enjoyed Crystal Downs, the first two holes have plenty of room for extra width that they don't use for some reason, and the 10th hole is cut such that the best angle of approach into the green is 10-15 yards into the right rough. Seems like an odd critique to me.
I wouldn't mind seeing some trees right of 15 cut down, though. But I think it's a very misunderstood hole, so I don't mind living with it.
I've played Kingsley, Greywalls, and Rustic. I love all three. They are very different sites and very hard to compare or contrast, but I think they each got just about a good a golf course as they possibly could have given the sites.
