AFAIK, Storm uses the "real" cores only from 14 lbs. upwards. If I remember correctly (not certain if it is still the case/state-of-the-art), lighter balls only have pancakes (no low RG cores at all, as Brunswick does with generic cores in their lighter offerings) and are sometimes marketed/sold as "leightweight", for some bucks less.
