I found this to be an interesting thread and quite surprising to read Ran's comments...I wonder if he still feels the same way? I can fully understand the PoV that in GB&I there will be a lot of weird, but cool courses filling out the 51-100 if I get to choose the courses. That said, I think the US has more of these weird and wonderful courses than folks generally acknowledged all those years ago. In the end, and as is always the case, it all depends on what one is looking for. I don't think there is any point in making "best architecture" arguments when what really matters is where does one want to play. Ths US is full of courses with good, but repetitive architecture that can be seen at tons of Tom, Dick and Harry places. An absolute boat load of good to very good courses would essentially cancel themselves out...why would folks include the same type and quality of course 25 times?
Just to give an idea the last few courses on my Happy 100: Castle Course, West Lancs, RAF, Sunny Old & Kingsbarns. I am confident these 5 would not be embarrassed by the botton five in the US.
