Inverted Fe2 Core


 
Storm Inverted Fe2 Core

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.
