It is a crap shoot, just as Notclay says. My stuff stays in the car year round and I have yet to have one crack. Latest in my arsenal are a Cell, A Rogue Cell, and a Grand Illusion. I have also had a Big Blue, Victory, Victory R, Torque and a Saturn stay out there. I have been bowling for over a decade. The only 2 balls ever to crack on me were the Battle, bad drill(cracked around a plug), and a Pioneer, it sat in a proshop waiting to get sold for 2 months.
