The Zone Classic is the better ball from what I have seen. The Smokin just seems to by too long which can mean squirty on some carry down. The ZC has consistent read and backend reaction whereas the Smokin can get really over/under on some conditions. The ZC can be used on a wider variety of conditions and patterns compared to the Smokin.
