I can't really specify for Sandpiper, just ocean frontage and pretty rolling property, Palmer as far as I can remember.
But for the Ledges, all it needed was a little variety. There are 9 holes on the cliffs 1500 feet above Huntsville, AL and the surrounding area, but the cliff is on the left side on each of the holes. Also, from the back tees, every par 4 plays between 405 and 459 yards, and proportionately the same from the shorter tees. I would much rather see a few shorter than 360 and some longer than 480. On the par 3s, I typically hit 3 iron, 6 iron, 6iron, 6 iron, 3 iron, in respective order. You could say play the holes from different tees, but the holes were not designed to play that way. Furthermore, the par 5 distances from the back tees, 600, 600, 575, 509. I suppose the par 5s would be better if I mixed up the distances my self, but that usually doesn't fly in my group. #15, 509 is an all-timer though, greatly rewarding a shot played to the correct side of the fairway. It could be even better if they cleared some of the trees behind the green offering a downhill approach to a skyline green, pretty unique. Beyond that, there are very few options at the Ledges, just hit it and go get it.
I also think the golf course is just toooo big. I think they could have used significantly less real estate to the extent of an even more dramatic effect.
I would love to see how Doak, Coore, Devries, etc. would have routed the golf course on that property. I grew up riding 4 wheelers on that land, and the possibilities are endless.
However, if you were to do a Top 100 most beautiful golf courses in the USA, it would be hard to overlook the Ledges if you have been there.
