Hi,
Back in October, I got a few new pieces, with one being a new T-zone. I have it drilled with grips and an exacticated thumb hole (poured around a silicone mold). Before christmas, this ball had already started to crack around the thumb hole, and is now missing a good chunk right above the thumb hole with a few rings of cracking around it. Its just a matter of time before it completely disintegrates. Before this, I had an old axis spareball, and it lasted forever, until I replaced the perfectly circular thumb hole drilled straight into the ball with a molded thumb hole that actually fit correctly. A few months after drilling it with the molded hole, it began to crack, the same as my current one is pretty much. Is there something about using a slug or molded thumb hole that makes them more likely to crack? or am I just having bad luck? Also, has anyone had any experience with a maxim or white dot cracking like this with a slug or mold thumb hole? I'd be willing to throw a different brand spare ball if it would las longer than this one.
