I am very curious about the Storm Gravity. Storm said that the Gravity is made from more durable materials. I was wondering if this is true or just more advertising on their part. I bowl on wooden lanes and get pretty tired of having to resurface balls after every 40-50 games due to track marks.
My vapor zone does not track up that badly and still performs like the day I got it.
Is this durability hooplah true?
