I have two of them, one drilled, and one undrilled waiting for the day when the first one dies. It's one of the best balls I've ever thrown. Smooth, controllable, and a has a backend that hits like a truck. It also has some amazing colors with the red-orange, indigo blue and charcoal grey.
In my opinion, the ball rolls nothing like what a Disturbed at 3000 would be. The Disturbed has a much more continuous arc, while the Nano Pearl focuses its power on the midlane-backend transition.
