yeah a 4x4 drilling is much too strong for this ball IMO. You could try a 5x3 or even a 6x5. The 5x3 is more of a "regular drilling" as in more people probably go with something similar too that, it would stick the pin somewhere in the middle of your fingers above or below. The 6x5 is used by people who tend too rev up the ball alot and want a ball to get down the lane before burning up, it generally would stick the pin somewhere over in your negative quadrant(somewhere over by your middle finger), this drilling keeps the track nice and tight. There are all different kinds of drillings you could try along with surface adjustments too make your ball go longer. You might want to check into the the dual angle drillings also.
