My wife has a Black Widow Bite that she loves when the lanes are oily, she would like a Pearl Bowling Ball when there is less oil, she only wants a 2 ball arsenal, suggestions ? She's a left handed down and in bowler, slower ball speed, very accurate.
              Thank you.

Arson Low Flare (control pearl)
Midnight Vibe (good length, more normal but not huge backend)

Sorry did not see this was is the hammer forum. So plus one for the arson low flare.

The new 900 Global Rip-It is worth looking into. Other good pearl options would be the Storm Fire Road, the new Track 503A, Hammer Arson Low Flare, and the 900 Dirty Look is another nice option though is a bit strong for the lighter conditions in my experience. Another choice would be to wait until May for the new Storm Freakin' Frantic to be released, it's a pearl shelled symmetrical ball with an apple scent I hear.

Hope this helps.

I haven"t thrown the Arson low flare,But I would suggest you consider the Midnight Vibe.The Vibe is a very controlable pearl,one of my all time favorites!
