Normally, skid-snap and heavy oil don't mix. You need dry in order to get the ball to turn that hard. No ball on the market is going to go 40 feet down the lane and make a 90 degree turn when there is a longer, voluminous oil pattern out there.
On that note, I would suggest that you look for the most angular ball for heavier conditions. Note that I did not say "heavy" -- in other words, these balls are not going to handle a flood. Only a particle ball, or a reactive that gets going super early, is going to handle a flood.
Storm's heavier oil stuff isn't actually that angular. Because of that, I would direct you towards a Roto Grip Epic Odyssey. It has the powerful, asymmetrical Maximus II core and a strong cover. Drilled properly, and with the right surface, it is most likely the most angular heavier condition ball available.
Other ideas I can think of are not AS angular in the back (not to say they are not good balls, however) -- Roto Grip SD-73 Classic, Brunswick Fury, MoRich Awesome Hook, and the Ebonite Infinite One.
Do note that I left Columbia, Track, Dynothane, and AMF out of the picture -- I just can't say get this ball when I don't know if you can. Track's Mean Machine makes a pretty good move, but the Odyssey is still stronger. Same thing goes for the semi-unreleased (the ABS Japan Web site has a video of it, but...) Threshold NGS by Dynothane.
Hope this helps.
