Second the pooh's suggestion of a label drilling. If it is her first fingertip ball, she won't have a PAP to exploit with a certain setup.
Put the CG in her palm, about 1/2" shifted towards PAP, and put the pin in a 30-45° degree from there towards the positive side, and in a safe area concerning the finger holes. No balance hole should be necessary. A 3-4" pin ball should end up with the pin in a pretty strong position next to or maybe even above the finger holes for some length.
This layout works for everyone and should yield some serious hook - rather arcing with a good end roll, a very good start for fingertip bowling.
From there, surface changes should tune the ball's utility, ut with its OOB polish it should already be "enough" even for higher oil volumes as long as the back end is clean.
