Just played Sipapu a couple of weeks ago. Hole 18 is both ridiculous and amazing at the same time. You have a straight wall of trees on both sides of the fairway. It is damn near impossible to get a good drive from the Pro tee-pads.
Parked it (from the pro tee it ended up about 15 feet to the left) with a beat up X-clone. Missed the putt though and I'm still kicking myself for that. You just have to remember to throw down at an angle. It is amazing especially when your disc keeps going and going.
You just have to remember to throw at the downward angle. I believe that the wind must have been blowing slightly from left to right on that day and that's what kept the X-Clone on line. But duplicating that shot would probably be very difficult. Just because it happened once doesn't mean that it will happen again.
I love solitude. One of my favorite course. We just got a new course in provo utah called jokers peak. It's still being worked on but its fun. Long and hard. Plays like a mountain course but since its a lower altitude its a lot harder to throw. Hole 12 is 1100 feet. The first half of the hole is up hill then a long throw flat throw to the basket. Its a legit part 5.
Well of our cities total of 2 courses, the 5th on our new course sucks it outta me, about 200 metres on an incline, all our holes are par 3, I finally parred it this past weekend, to get a birdie im gonna have to nail it from 100 meters uphill.
