Pitching machine balls can be much harder than regular softballs. Regardless of ball type, a bat can take only so many collisions before it breaks, composites generally are less durable than metal bats. Try and buy a beat up version of your DD's game bat and dedicate it for cage use. That way she be practicing with the same model and weight she's using in games and you're not out big bucks when the beater dies. As kids get older and stronger and play/practice more, don't count on their bats lasting more than a year.
