The WOW Pearl is, in my opinion, a very unique piece of equipment. First of all, the Pearl Particle shell (UFO Pearl) coverstock works great. It is aggressive in oil and not too aggressive in dry - this makes for supreme control without sacrifice of power.
The thing I like most about this ball is the way it retains its axis rotation longer than expected. When other balls have turned over and are in the process of losing energy, the WOW Pearl is still rotating on it's original axis rotation, even when it's starting to hook. This helps the ball retain more of its power for the backend. The ball goes into a very strong roll on the backend, but because it has saved its energy exceptionally well, does not roll out. It seems to keep coming longer than other balls. I haven't seen many other balls that tend to do this same thing, but the one that sticks out in my mind is the original 3-D Violet Offset Hammer. The WOW Pearl seems like it reacts very similar to that ball, just a bit stronger.
My WOW Pearl came with a 5" pin-to-CG distance. I put the pin about 1 1/2 inches above my bridge, slightly biased towards the middle finger. The CG is kicked out 2 inches from the center of the grip. Because of the low starting top weight (2.25 oz.) I do not need an extra hole in the ball despite the offset CG. The final specs are == 6" X 4" X 4 1/4" == (pin from PAP X CG from PAP X pin above midline)
(I threw that last one in because I don't believe that pin and CG from PAP are enough - pin distance above the midline is extremely important also in my opinion, as a lower pin results in earlier hook).
