Hard to say without seeing her throw. Basic statement I make , after several questions...pin not to high ( depending on the oil/ball) and right of ring.
KEEP IN MIND...only someone who has seen her throw, knows her style, is there watching her or measures her PAP should really be making that suggestion. Best I could offer is go talk to your pro shop guy.
