I know nothing about Country Club of Troy and I don't care about the ratings, but I do have some thoughts on why Cypress Point is a much better golf course than all but a relatively small number of golf courses anywhere.
1. The setting. Others have mentioned aesthetics, and the aesthetics are unparalleled, and that certainly matters. But focusing solely on the aesthetics sells CPC short. To mention just a few examples, the course is seaside, and so it is subjected to seaside winds and weather, and that is a huge plus for golf in my book. The setting also insures that the course will seldom play the same for day to day or even hour to hour. The course is built on and around sand dunes, the proper setting for golf, so proper turf conditions can be somewhat replicated. The ground itself is interesting and provides plenty of opportunities for exciting golf course architecture.
2. The architecture. The course flows over and through these dunes smoothly and seemlessly, so one gets the sense going on an adventure through nature, another big plus by me. The walk is intuitive, easy, and possibly the one of the most most visually spectacular in the world. The routing takes full advantage of the natural features, creating the type of memorable, exciting and unforgettable shots. The holes and the greens present tremendous variety. Every hole has its own distinctive personality, and all present a variety of challenges depending upon the conditions at the time. The holes fit together cohesively. Etc.
Is Country Club of Troy seaside? Is it built on or around giant seaside sand dunes? Are there constantly changing seaside conditions? Is the walk one of the most spectacular anywhere? Does the course offer tremendous variety where each of the holes (and greens) have their own character? Does the course present shot after shot that the golfer will remember forever?
In short, Cypress is a combination of great golf course architecture in an ideal setting for golf, but the ideal setting goes well beyond the aesthetics. Some courses built in nice settings don't match it in terms of architecture. Other courses with great architecture don't match it in terms of the ideal setting for golf.
As for your 5-5 split, if you find ever yourself in a position to pass up 5 rounds at CPC, please send them my way.
