If you are looking for a good 2 ball arsenal in the Brunswick line for PBA patterns, I would suggest a pin up drilling on a Nexus f(p) pearl and a pin down versa max.  The versa max is a smooth rolling ball and even with the pin down drilling, it shouldn't hook early.  The Nexus pearl will give you the extra length with a strong backend movement.  The other good 2 ball arsenal would be a pin down Reckless which you can adjust surfaces depending on the pattern, and a pin up Too Reckless.  The Too Reckless will clear the heads a give you a strong backend movement.  If you are looking for an overall stronger ball, I would suggest the Hell Raiser Revenge or Nexxus f(p+r).  They can handle to higher volumes of oil and take well to coverstock changes by either polishing or sanding them.  You can't go wrong with a DV8 or Brunswick ball.
