I would not spend $65 on a bat for an 8yr old, but thats just me. The bat will play very little part in your daughters success at this age. Go to wal-mart and find a "pretty" bat that is not to heavy for $15-$20 and call it a day.
Good luck!
This what I'm thinking too. She is small for her age and is just growing into the youth bats instead of T-ball bats. The reason I asked about the mayhem was, it is the smallest 27/15 bat at our local sporting goods store. They have cheaper bats, but she can't swing them yet.
When my DD was 8, we went to walmart and got a
purple bat with pink lettering for $15. Replaced it with
a decent bat ($75) when she was in her 2nd year of 10U.
Spent $150 in 12U she grew like crazy into a Stealth
the following year and now just bought her a CF4.
She has hit well with all the bats
