Peter,
Could you please elaborate on the similarities you see? The bunkering doesn't just look different, the two styles are completely unrelated. The deep, high faced bunkers of RM and the flatter, rounder look of Pinehurst.
I don't remember the RM green complexes as being akin to Pinehurst either, the RM greens aren't all convex like that.
It seems to me that Pinehurst fairways are flatter, narrower, and straighter.
What in the strategies do you see as alike?
