It starts with the ball and the greens. I cannot imagine somebody backing up a Pinnacle or a Molitor anytime soon unless the greens are in primo shape and there's an upslope of the green on the approach shot and the fairway grass is in primo shape as well.
It's not that big of a deal. I can spin the ball with ease (provided I'm on a decent course) if I want to, but there's rarely an advantage to it. Duval spinned one off the green today, it's more of how a shot plays than trying to do it to gain an advantage. Sort of like hitting a driver down the right side on a fairway that slopes quite a bit right to left. They are not actively trying to get the ball to roll down the left, they are just playing the slope.
