When you say she is having a hard time getting the Pyscho to react, I will assume you mean that she cannot get the ball the flip on the backend. From what I have seen, the Psycho tends to react better with pin down drillings and with some surface. IMO, the ball OOB with a pin up drilling would be very hard to get the ball to corner for most people. I would suggest trying surface or even redrilling the ball with an earlier layout.
I have thrown the Cell Pearl and the Rapid Fire Pearl. I think that the Cell Pearl is better to open up the lanes and bump the friction, and the RFP is better when cutting the heads fairly straight.
Hope this answers some question.
