SGD:
I think your assesments are pretty good, though I have a couple points of disagreement.
I think you put Wente far too high, and the Ridge far too low. Wente is one of those courses that I just don't get people's affection for. It's a bad routing on a bad site; the greens and bunkers are okay, but nothing to leap up and down about. There are just too many bad holes (4, 6, 13, 14, 16-18) to be anything more than a 5.
As for the Ridge, did you not love the shot options? There is hardly a bad hole out there, though 6,7,8 on the front are too similar and 2 and 9 are rather bland. But the back nine and middle part of the front nine are outstanding, especially 10-13.
I also think you have Saddle Creek too low; that course just rocks, I don't care what you say. Still, the only course on your list I haven't played is Winchester, and I'll hopefully see that in the next few weeks.
