From the current Brunswick balls, the Punisher with the same specs and layout will be the closest thing to the Frenzy - it is its direct successor. Other balls that might do the job are the Smokin' Inferno (a kind of high end solution, overall moer powerful but similar reaction) or a MoRich Sahara (same cover as Punisher, just a strong MB core with more pop from MoRich). Mabe the new Radical Inferno might also be an option, since it is also quite snappy and from what I have heard from Brunswick staffers around here needs a strong drilling - might also be similar in reaction to the Frenzy.
I am just wondering that your Frenzy goes "above" your AI? It might be snappier, but not handle as much or long oil? (At least, it should not do so by design?).
Hope this helps a bit?
