You won't see many of them of in the stores, but you might want to see if you can get your hands on a -9 or -8 LXT. They have the 30-day guarantee so you won't be out anything if she doesn't dig the feel.
She is 13 and hits farther than me, I am 6'4" 230 Lbs...lol. Tomorrow cant get here fast enough.
I am on the same boat right now. My DD swings a 04 RT 32" it weighs 25.6oz. She is wanting to transition to composite bat for HS and 16u. Her #2 bat right now is an older CF4i 33/23. I am thinking about either 33/24 or 34/24. She is steering toward new Xeno but I am old school so I wanting her to try some of the older Eastons Stealths (scn6b or scn7b, maybe a 4)
