The pins aren't always going to willingly lay down for you. Sometimes they put up a fight. So in development of our new Fight bowling ball, we explored some engineering concepts related to core volume, and were able to show through testing that this concept worked in creating a different break point position and shape. The difference with the Iron Cross™ weight block is that it is the largest weight block Storm has ever developed. And while it was challenging to create this much flare potential in a design which retains this much axis rotation, we're confident you'll see the benefits.
