Bruce,
I recall debating just how wide to make that valley, and eventually widening it just enough to where a pin could be put down there every once in a while for fun. After all, it is a resort course, meant for fun.
At Fox Chapel, I think the valley is similarly pinned on occaision, but most Raynor Biaritz swales aren't. As always, I could be wrong. Either way, its a case of me taking what I like from the templates, and ddoing what I want with them to make the best design possible.
