I've played quite a few Arthur Hills courses, mostly due to proximity to a lot of them since a lot of his work is in the Midwest. Here's my take on the few I've played:
Weatherwax--decent public track in southern Ohio. Not great, but some good holes and a nice value
Shaker Run--agree with most of the sentiment that it's overrated
Longaberger--played it this spring in terrible conditions, but I really enjoyed it. This is by far my favorite of the courses he's done. I thought there was a good variety of holes, strategic use of hazards
Pipestone--played it once. After I hit what I thought was a perfect tee shot on the par 5 (2nd hole?) down the right side and ended up in the water hazard to the left, I was pretty much done with it
Bay Harbor--glad I paid the early season rate
Links @ Lighthouse Sound--it's been probably close to 10 years since I played this course, but I remember liking it. The only thing I didn't like, as an avid walker, was that I don't think it was even remotely close to walkable
I'm planning on going to Egypt Valley at some point this fall. I've not heard one good thing about it, so I feel like it's worth the trip just to see what all the fuss is about...
