Hmmm, for a ball, I'd suggest a mild reactive ball like the Brunswick Power Grooves, but other manufacturers have also good antry balls with reactive coverstock and high RG cores.
Back up balls are common among women... I suppose it is the broader waist? And I have read somewhere that it was because women would naturally tend to put their hands next to their legs when they sit, while men do different things... dunno.
In fact, a friend of mine who started bowling with a conventional grip and even with a fingertip reactive (also 12 lbs., an Eraser Boost with a rather aggressive drilling) used to produce a back up ball and a reverse hook.
Then she got a wrist support/glove for her forearm from her friend which covers her index finger and pinky (a blue one, I do not remember the manufacturer and model at the moment), and it became immediately better. She is a low track bowler, with low speed, and now she averages 140-150. Although she still tends to have a reverse hook with her spare ball every now and then...
So, I'd suggest asking a pro-shop proprietor and/or a trainer for advice - either for a new ball and a matching drilling, and maybe for solutions concerning the release. I'd guess that a stiff wrist support will be a step forward.
