Just based on your comments in this thread, I'm guessing your DD is a damn fine hitter no matter which bat is in her hands. The reality is that the top-shelf model from any manufacturer is going to be a good bat, and it will come down to personal preference on subjective factors like feel.
My DD is 16, and about the same specs as yours. Similarly, she has the speed to turn triples into doubles. Her preference is the Ghost, hasn't met an LS she likes, and is pretty luke-warm about Demarinis.
Of course you have to be able to hit. Good or bad, feedback is important though. I wish I could say my DD hits 4 HRs every tourney, but that wouldn't be a true statement.
