The hitting power is unmistakable in the Inverted Fe2 Technology with its heightened coefficient of restitution. The R2S Hybrid Reactive has become pillar of consistency utilized in some of Storm’s most successful balls in recent

Smartly designed Inverted Fe² Technology

Inverted Fe2 technology boasts a higher RG and differential like most other balls in the Thunder Line, but with one very important benefit: it lacks the core material that most other balls have. This enables the ball to have a much thicker shell which raises the coefficient of restitution. A higher energy transfer to the pins with less deflection upon impact is what can be expected with this design.
