IMO Assassin, I changed the surface on mine to 300 because sometimes it read the oil too soon and used to energy leaving 7 pins, weak ones and some other it would just dont make the turn in time, by changing the surface, omg.. stores the energy and the realease it like a damn mule!! plus it kill the oil quickly, Im a high rev high and continously have to keep up with transition, today.. no transition at all with the 3000 finish.
Summary:
Stores large amount of energy, can play the inside or outside part of the lane with no problem and more important... nice pin carry with massive back end!
Either ball, you cant go wrong with a BW
