Best bat size - length vs weight

[kcsoftballdad]

My daughter plays high school and competitive club fastpitch. She is about 5'5" and weighs 125lbs. She currently hits with a Demarini CF4 drop 10 32x22.

She is thinking about moving up to a bigger bat - either a drop 9 32"x23oz, or a drop 10 33"x23oz.

Both bats feel comforable to her. Which is the better choice - the drop 9 32"x23 (which might have more pop), or the drop 10 33x23 (which gives her better plate coverage)?

I am not sure what coaches would recommend. Advice would be appreciated.

Why does she want to move to a bigger bat? Is she hitting ok but wants to hit more HR's? Does she want more oomph out of her hits? This may be accomplished with technique and not a new bat. You may be better of spending the money on swing analysis and/or lessons.

Try to get to a cage that has demo bats to tryout, or a teammate that has a bat she likes - she may end up not liking what she thinks she likes.
