Storm Purple Pearl Hit Bowling Ball

Got this ball for my girlfriend as her first fingertip ball, and to teach her how to throw a hook. Didn't really expect much, but it blew me away what this ball does. She throws pretty slow(around 14 to 15), and you might say she's "rev-challenged" but, on our typical medium to heavy house shot, it's a hook monster for her. If she throws inside of 10 with her normal rotation it'll hook into the gutter, or at best take out the 4-7-8. Depending on the amount of oil, if she puts it from 5 to 10 it creams the pocket. Now this is a 10 lb ball, mind you, and she does leave a lot of single pin spares due to deflection, but she's striking more than ever, and seems to be naturally able to kill most of her revs so the ball rolls almost perfectly straight for spares. It's a normal drilling with about a 4" pin, next to the ring finger, and the CG just right of center. The first time I saw it move I thought "This is a light oil ball?" Makes me wonder what she'd do with a ball meant for floods
