my girlfriend throws 13lbs, and right now she's got a super charge. i know most companies change the cores of the ball after they get below 14lbs, is this also true with storm? i've emailed them and have gotten no reponse. i've searched the storm website and i can't find any info on this topic. the only company i really know of that doesn't do this is brunswick. if this is true, does anyone have any information on what the core of a 13lb super charge looks like? thanks.
