Well, I am biased towards Crystal Downs from growing up and working there, but I still have to take them after all I have seen.The University of Michigan's greens are very good, but not what they were 65 years ago. The recent "restoration" did not touch the current green surfaces but they also did not restore the greens to their original margins and affected areas adjacent to the greens during bunker construction and drainage work. The best example of where they missed is at the "boomerang" 6th, where the back portion of the green should have been brought back out further for a great, difficult pin. Instead, there is a swale there that controls drainage away from the green. It functions well, but loses a GREAT pin. Also, the course is fun and diverse, yet cramped on the site in several areas for the amount of play it now receives, still has way too many trees, and is still used for football parking in the rough during home games at The Big House, so you can imagine what a rainy day can potentially do.
