I truly believe the most interesting holes would be the ones with green sites where you play not from the opposite direction (180*), but from the side (80-130*). An example of a green that I think would be incredible to play from a different angle is the 18th at Pacific Dunes. It's obviously a very strong green site from the original direction of play, but from the back tee on the first hole is also a very interesting angle.
Mike:
Indeed, that's what we've found at Forest Dunes.
Originally I was trying to keep the routing as simple as possible, changing direction as little as possible, because when you get to a corner, you can no longer use the same tees for both directions without having crossovers. However, there was just enough topography at Forest Dunes that the second iteration of the routing plan, trying to utilize more of it, created more changes of direction; and I realized quickly that these would be to the benefit of the course, as there are vastly more types of greens that work for holes 90 degrees apart, than for holes 180 degrees apart.
I also soon realized that there was no need to combine tees; if a hole needs two separate sets of tees to be played in the two directions, that's fine, because each of them only has to take half the traffic, so it only needs to be half the size.
Mike: Thanks for posting this plan, which I'd been told about but never seen until now. It looks like Travis did not have to worry so much about crossovers and cart paths, as we've had to.
