The problem with talking about a routing is very few of us are in a position to know what is a good or bad routing given the constraints of a given project. Sure, we can talk about the walk in the park or rhythm aspects of a routing, but getting into the hows and whys of a routing really should be left off the table unless one knows the project very well.

And that's one of the reasons ROUTING is the most underrated aspect of golf architecture on this site, because it's so hard to discuss.
The routing is far and away the most important part of the design. If you get the routing right, you get the drainage right, you get the forward tees right, and you ought to get the green complexes right because you're in a good place to build a green. And no one has mentioned it yet, but you get the construction budget right, which is a key part of any project's ability to survive. It's even a lot easier to get the mowing lines right, if you think that's the most important thing.
To me, the one aspect that gets more and more important as I get more experienced is the transition from one hole to the next. If it's really good and seamless, you don't even think about them, and you don't get out of the flow of enjoying yourself on the course or of playing well. If you get the transitions wrong, the enjoyment goes down markedly. And the transitions, of course, are the ROUTING, too.
