You might have better luck looking for a CF6.
CFs have outstanding resale value. You'll get $125 - 150 back on that bat easily.Closeout bats has CF6 -11 in her size for $229. I wouldn’t spend that much on a bat yet but it would be a really nice bat for her.
Petite? Your DD is a giant compared to my twig, lol! Mines 4-9 and 62-63lbs. Last year she was in the 80th percentile in height and 4th percentile in weight. Let me know if you find something because I'm looking for something. Probably 30" 18oz with minus 12.
I've got a 30/20 Xeno DD outgrew. $100 + shipping if you're interested.
