So my daughter is 5'0 about 95lbs, she is a gap to gap type hitter, but does have some pop. I am looking at getting a new bat for Xmas and have focused on the 2021 Demarini CF either 30in or 31in -11/-10 or the 2020 CF version. What are the differences, is it really going to be worth the extra cash to get the newest version? She is currently swinging the Bustos 30in -13, it is very easy for her to swing but the ball seems to die off of even very solid contact. Just looking for any ideas or advice, on models and which drop would probably be best. Thanks in Advance.
