I just had another one crack. A Storm Meteor from 1997. I've been throwing it faithfully for the last few months. Choose to go back up to 15lbs and took the Meteor and removed the inserts and put it in the upstairs bedroom closet with the rest of my balls.
Within a month it cracked from the seam where the resin and outer core meet, up and out all the way out about 3 inches.
This was after I removed the finger inserts, and cleaned up the hole.
Ball lasted 15 years with no problems. Used it a bunch this year, as soon as I put it away it cracks. As of today it's still cracking, making its way around the ball slowly each week.
No bowling ball is safe. Doesn't matter who makes it, or what its made when it comes to thickness of resin.
