Bill, Isn't it more than just the greens? More precisely, where the pin positions are for a particular day/event. And, isn't the normal 6,6 &6 set-up standard. 6 easy, 6 hard and 6 medium. When the ratio gets shifted to more than 6 difficult pin positions, you'll usually start to hear the whines a' crack'in.
Also, the maintenance aspect, or firmness, isn't really tricked-up, it just is what it is. The fact that it didn't rain, when forcasted, the Saturday night before Father's day, on a small section of Laang Island, doesn't really qualify as a trick. Other than by mother nature.
