Other Thoughts:
Fort Buhlow Purple is a solid course, that won't bore you half to death like the other course at this location. Starting with four short and tight tunnel shots through the trees and ending with longer open shots, this is a nicely balanced course. The designers did a good job of balancing left and right favoring holes as well.
Bigger arms will have an advantage on this course, especially on the back 9. For example, hole 7, which is open for about 375 feet but wooded for the last 150 feet or so with not too wide of a fairway; the closer you can get to the woods on your drive, the less luck you'll need to reach the basket for the 3. Similarly, 16, 17 and 18 will be much easier the longer your drive is.
I liked the stretch of holes along the bayou starting on hole 10. There are risky but possibly rewarding routes to the pin on 10, 12, and 13 that go over water or by trees near the water that can kick discs in if the shot isn't precise. Hole 10 is possibly the most memorable hole on the Purple course, with a long safe lefty route or a straight route over the bayou about 280 with a steep bank to clear at the end.
I'm not a big fan of Hole 9 on Purple, which is a downhill lefty bomb. While it's a decent hole, I'd much rather see the pin moved to a straight position, where a fun, throw-it-as-hard-as-you-can shot that players could watch for a long time in the air could be had. And the lack of multiple pin placements on this course is what keeps Purple at 4 stars rather than 4.5 for me.
