My 10-year old loves her CF6 Sprite (30/19) and is killing the ball with it. I bought it a year ago last august when she just turned 9 and it felt a little heavy to her, but by the following spring it wasn't too heavy and then she really started hitting this summer and now fall. So right now it is the perfect bat. However, she's growing and my guess is it will be too small for her next spring or summer, and I'd rather buy a bat this fall. My question is how far up in size do you go? And then would you go with a CF8 or take a look at other bats? She'll be 11 in June. Right now she's about 4'9" and 70 lbs. Not super strong, but fast hands.
