well if u ever have the chance to sit down and listen the entry level coachin, then do it!
i think u can help a lot when it comes to basics, if u want her to bowl better, pay close attention to her straight game, for strike and spare, and body coordination.
and when it comes to balls to choose... whatever fits imo, something i hate seein from a person is a nice shot for strike but cant throw for spares, specially corner pins.

When a house bowler misses the mark, misses the break point and strike, for many ppl its called a wallshot. When a pro does that its call adjustment
When a house bowler gets his finger stuck in the ball and fall on the lanes, for many ppl its called lame bowler. When a pro does that its called the Machuga flop! ha i like this one.
