Pros:
First and foremost my hats of to Bill for keeping this course as pristine as it is, and for so long. Bill really has a passion for disc golf and to share this truly tremendous course with everyone is beyond gracious. You can instantly see when you pull up to the course, everything is meticulous, from the fairways to the paths cut into the rough for wayward discs. As your conquer Flip, it takes you on a visually stunning hike through some of the best that northern Michigan has to offer. The first three to four holes are deceiving to how the rest of the course unfolds. As your walking to hole 5's basket, you instantly see how breath taking this course truly is. Not only is this course visually stunning, but it tests your shot selection almost every hole. Just about every tee pad has a broom to clear away debris. Making your way from one hole to the next is easily done with out a map. Granted the Ams and Womens tees are hard to find, as they're just noted by rocks in the fairway. The pro pads are in great shape, and even have a foul and follow through built into the concrete. The signs that show how the hole plays out are very nice, I wouldn't say they are as nice as Idlewild, but they do a great job. I can honestly say while playing Flip, you almost have this feel about you, like a feel good mystique about this course. Another nice touch to the course are what I would call welcome stations, that allow you to catch your breath and take in the true beauty of the course. There is also the sign in shelter on 2A. Another fun aspect to playing Flip is the pin placement. As frustrating as they are they add yet another element to your putting game. Hole 4 is probably the best example of this, if your approach or putt hits wrong, you have a solid chance of rolling down to almost the tee pad. Hole 4 is just the beginning of the great pin placement. This course also has it's fair share of blind holes to throw on as well, my favorite was after finishing 17, you get to ring the bell to signal that you've finished. The landscape of Flip is through out a forest, and it takes full advantage of using the foliage to test your shot making ability. Never does it make it look like a pin ball shot and a great deal of luck is needed to have a good shot.
Cons:
As others have mentioned having more defined OB would make this course a little more challenging. I really liked how Idlewild accomplished this. The rock sculptures are OB, and very creative at that. This isn't the hardest course I've played, but it will take it's toll on you in a fun and rewarding way.
Other Thoughts:
I wanted to wait and review Flip to I was able to play Idlewild to have another top ten course to compare it to. Idlewild is hands down a championship caliber course. Probably one of the hardest courses I've played. I would rate Idlewild a 4.5, because it doesn't have the same feel to it as Flip does. Really what more can be said that hasn't been said in the hundred plus reviews before this. 45 minutes north of Flip is yet another 4, 4+ rated courses in the Luddington area, which I HIGHLY recommend playing!! Seriously do yourself a favor and make the trek, you won't regret this pure Michigan experience.
