The Sure Lock will produce a visible, discernible motion that bowlers from all skill levels will be able to see. The RAD-X Core brings real substance – a fast, tight spin radius with no shortage of movement down the lane. With the Sure Lock in your hands, your carry percentage is sure to go through the roof.
GI-17 Solid Coverstock
The GI-17 (Game Improvement - 2017) is an exclusive chemical formula for Storm in 2017. Its tenacity has been engineered specifically for battling heavy oil and generating mid-lane roll. The top bowlers in the world are renowned for controlling the midlane and this coverstock formulation will help with exactly that.
RAD-X Core

Flare potential is synonymous with the RAD-X name. Its dynamic design with super-dense materials produces superior hook and ball motion. There is no shortage of power in this engine. With over 6 inches of flare potential ready to be unleashed, the player will be able to create a ball motion that demands attention.
