I had a greenie crack once. started at the thumb hole and just kept on going. Yes there was a slug in the hole, but I've installed many slugs and this is the only one that it ever happened to. that being said I also have owned many Visionary balls, from the days of the warlocks etc. and this is the only one I've ever had crack. Visionary has some of the most durable coverstocks ever created.
