I love Hurstbourne Country Club and when they have those greens running fast, it is a real challenge. I have not played Lassing Point nor Paducah CC, but I can't imagine them being a better test of golf than Champions.
Lexington Country Club is in fantastic condition, and is a great country club, but I still rank Champions higher.
Olde Stone should be in any top five in Kentucky.
Champions and Keene Run are both part of the same club. Two courses. Not a fan of Keene Run, but I play it fairly often.
