IMO that CF6 Sprite -11 is an amazing bat. My DD has the 32/21 model and has hit several HR with it, even thought it's -11. Durability is great as well, still carries that bat in her bag 4 years later and still can hit lasers with it.
Got the LS lxt when she moved to a -10, and it's been a sold dependable bat as well, got the lxt cause we weren't fans of the CF7.
She now swings a Ghost from Core, but those two bats are always in the dugout incase there is a problem (our ghost hasn't had any issues).
Finding a decent bag to carry all the bats, now that's another story.
