Brian,
For another course to do as Pinehurst, it would need to have a similar environmental conditions.
But for all other courses, I think it all starts with water. If a club wants to do "as Pinehurst" it starts with cutting back the water, way back, and then adapting the course to the new water regime. It really is a simple mandate, but a complex problem to solve.
I like Matt Shaffer's (Supt Merion) quote "“Water is the root of all evil,” he says. “It starts the cycle. You’re flushing nutrients with a tremendous amount of water, so you lose all of them. Then it becomes more succulent so you get more disease. But when you pull the water out, you’re going to lose some grass.”
Change the cycle and you change the course.
