Hey, this is my thread and I will define "flat" as I see fit!!!
For this discussion, "flat" means that the difference between the lowest point and the highest point, PER HOLE, is no more than 10 feet. That excludes OB and hazards, which means if it has a bunker that is more than 10 feet deep, it still qualifies.
Rolling lands are fine as long as they don't roll more than 10 feet.
What I am really interested in is this: if you can see every part of the hole from any part of the playing area, it takes a huge amount of strategy and drama from a hole. So, how do these great flat courses do to compensate for that lack of strategy?
