I'm not sure reversing the nines at Spyglass helps that much. Then it's just a great stretch at the start of the back nine. At least having the great stretch of holes first as it is now is memorable, and the first hole tee shot is really a great one. I suppose 9 is fractionally more interesting than 18. But still, I don't think that's a winner and even just for the sake of continuity, I would prefer they leave it as is.
That said, I do think it's the poster child for why a strong finish is preferred. If you played Spyglass 6-18, 1-5, I think you'd see a lot more praise for the course, because there are plenty of good holes back in the trees and it would all be "building toward the tremendous finish out in the dunes."
