In the last five months I have had three Storm balls crack completely around the ball while resting in a climate controlled environment and rotated every month.. I tried to find if there was any similarities like the same coverstock, all symmetrical vs. asymmetrical, solids vs. hybirds vs. pearls, same cores, or that the balls came from the same line e.g. Premier, Master, Thunder, etc. that the balls might have shared, I could not find any similarities other than all three were produced from 2012-2014 time period.
Lost the IQ Tour Edition Solid, Firestorm Pearl, and Crux Hybird. I'm going to Staples tomorrow and buy some clears plastic bags for small desk wastepaper cans and put all my many remaining balls in plastic to see if that stops what has occurred. It's worth a try as you all know how expensive these balls are.
