The new Mix balls, available in two different colors, expand the Ice line with a new look and feel. The Mix, like the Polar Ice, features a durable U1S first generation urethane coverstock which is more controllable than U2S which powers the popular Natural series. The Mixs traditional 3-piece core enhances predictability while the urethane coverstock ensures durability that other materials just cant offer. And they are available in lighter weights. In addition to the standard 10-16 pound options, Storm is pleased to offer both 6 and 8 pound options as well.
