A friend of mine just picked up an Easton Stealth Clarity SSR1B for me for $50 on craigslist. It looks practically brand new. This will be my daughter's first composite bat and it looks like it will need some breaking in. Other than just having her use it in practices and games what should/could I do to speed it up. She and I could put 300 hits into it in an afternoon and have fun doing it. Is it ok if I take half the swings? I am a pretty big guy and I can swing way harder than any 10 year old girl. Am I going to hurt the bat if I turn it loose? It is a 30/20.
