- Mix 

First Impressions
The Storm Mix was introduced in July 2013 as a versatile addition to the lineup and fills the niche between straight polyester and mild urethane. The look is kept simple, while the cover is made from a special urethane blend finished with a 3500-grit polish out of the box. Inside sits the proven symmetrical Traditional 3-Piece Core, which provides a calm and predictable ball motion. The specs at 15 pounds show a 2.69 RG and a very low differential of 0.006. This combination results in a ball designed for minimal friction and extremely low flare potential, with the urethane material promising slightly better durability and improved bite on the lane surface compared to conventional plastic.
Comparison Compared to a classic polyester ball like the Storm Ice Storm, the Storm Mix offers somewhat more controlled movement on the backend thanks to its urethane shell. Where straight plastic can often slide uncontrollably, the urethane of the Mix provides a more subtle interaction with the friction. Placed alongside a performance urethane ball such as the Storm Pitch Black, it becomes clear that the Mix generates considerably less overall hook and responds noticeably later to the transition. Compared to a weak entry-level ball with a reactive cover, such as the Storm Tropical Breeze from the same era, the Mix shows a far straighter path without the typical change of direction at the end of the oil pattern. It therefore acts as a bridge for bowlers who find polyester too short on traction and reactive material already too lively on dry boards.
On the Lanes The ideal use case for the Storm Mix is spare shooting, especially on difficult spare leaves. It is aimed at all player types looking for a reliable ball for the pocket when the lanes are extremely dry or when an absolutely straight path to the pins is required. Thanks to the urethane cover, it generates slightly better carry on spares than conventional plastic balls, since it is less prone to deflecting off the pins. On very short oil patterns or extremely burned-up heads it can also be repurposed as a strike ball to avoid an overreaction on the backend. It gives bowlers with a high rev rate the control needed to attack the pocket without taking a big detour. Its rugged construction makes it a long-lasting companion for any bowler who values precise repeatability of his shots, regardless of the transition present on the lane.
