I've enjoyed reading others' takes on some of the courses that I've played. Some that I really disagree with (i.e. Pine Needles a 5), but that's to be expected. I always find it hard to assign a course a number because I feel that so many fall between the categories. I'll just give my list with some additional commentary when I thought that a course was noteworthy.
I'm also thinking of posting a full pictorial write-up of American Dunes on this site if anyone would be interested in that.
Whistling Straits (Straits): 7. Obviously it's an excellent course with several fine holes along the water. I was concerned about the par 3s being too similar but that wasn't a problem at all because while they're all on the water, the elevation change varies between them. But the narrowing of the fairways for tournaments has made it too narrow in spots and more generally, some of the holes on the water felt like they were on awkwardly narrow shelves (i.e. 4). 5 is one of the worst holes that I've ever played. Still, the best course that I played this year.
Meadowbrook: 7. Just down the street from my father's house, I was excited to finally play here this year. It's just a very thoughtful golf course. The greens contouring is very well done, the bunkers are well-placed and not excessive, and there's good give-and-take between hard and easy. Because of the shaping style, the obvious point of comparison in Michigan is Arcadia Bluffs-South. I liked this course more, in large part because of the restrained bunkering. I don't love the angular shaping given the broad contours of the site and some of the green edges were a bit severe, but it's an excellent course.
American Dunes: 7. I played this course twice and my takeaway was that it might be the best public course in Michigan. There are probably a few too many water holes for some on here but except for 18, I liked them. The strength of the course is in the middle of each 9, with some very good par 3s and some of the best par 4s in the state (5, 11, 16). I also like the two fall-away greens on the par 5s nos. 2 and 13. Walkable and critical that you do so that you don't have to hear Jack Nicklaus bragging about himself on the GPS screen as you approach each tee.
Keilir: 6. Not worth the trip to Iceland in itself, but definitely worth taking a day to play while you're there. I could convince myself that it's a 7 because there are several great holes and an excellent set of greens. It may be hard to argue otherwise when they complete the new par 5 and par 3 that they're planning on the cliff's edge on the back nine.
Indianwood (Old): 6. Being from Michigan, I've wanted to play here for years and it was nice to have the chance. It's a beautiful property and there are some very good holes but it's looking a bit exhausted at the moment, with shrunken mowing lines everywhere.
Bulle Rock: 6. Probably the best piece of property that I've seen for a Dye course and unlike some of the other Dye courses that I played this year (Irish, Barefoot), it was nicely restrained. Not sure that there were any great holes, but there were many very good ones (1, 3, 10, 11, 14, 17).
Warren Course: 6
Dunes Golf and Beach Club: 6. Everyone says that this is the best course in Myrtle Beach but I can't see putting it above Caledonia. It's an excellent course for a good player; you have to drive the ball straight and hit high, soft iron shots because most greens are bunkered across the front. But there wasn't anything particularly interesting about the design other than the 13th hole. It felt like the other Trent Jones courses that I've played, but on a very nice property.
Brautarholt: 6. My initial thinking was lower because holes 10-12 are mundane and the routing is awkward on the main 9, but there are too many very good-to-great holes for this to be less than a 6. The long par 3 5th over the beach must be one of the world's best.
True Blue: 6. Definitely a borderline 5/6. I appreciated the restrained shaping and there are some very good holes, but the routing is awful and the last 3 holes are just overdone.
Whistling Straits (Irish): 5
Barefoot (Dye): 5
Barefoot (Love): 5
Tidewater: 5. 6 for the individual holes, -1 for the routing.
Stonewall (VA): 5
King's North: 5
Blue Mash: 5. Maybe the only Arthur Hills course that I've played without a severe flaw in the routing. Over-mounded and a few awkward, narrow short par 4s. But it's mostly solid. Better than almost all of the Hills courses in Michigan.
Lake Presidential: 4. Supposed to be the best public course in the DC area...it isn't. They let me walk it, which was a terrible idea; it must have been a half mile walk around the pond on 18 just to get from the tee to the fairway. Greens are often a bizarre concave-inside-convex; if you hit the green the ball funnels inward but if you just miss it, it runs away. Some very good holes but a few awful ones too (1, 14).
Worthington Manor: 4
Twin Lakes (Oaks and Lakes): 4
The Ravines: 4
Hawkshead: 4
Raspberry Falls: 4
Clustered Spires: 4
Myrtlewood (Pines): 4
Glen Mills: 0/4. I thought that they were really onto something here in the first 5 holes but then it just goes so bad, with several fairways with about 60 ft. of landing area width. Probably not much that they could do given the property and there's some compensation in the form of some very good holes and greens (except no. eight). But they probably shouldn't have built a course here and I wouldn't want to play it again.
Rattlewood: 3
Bramblewood: 3
