The most forceful symmetrical ball in Storm’s line, the Optimus Solid commands respect. The Tri-Sphere core is unique and powerful, aggressive yet predictable. Thanks to the superior traction of the R2X Solid shell, grip in oil is no longer an area of concern.
This core brings new meaning to the term “power personified.” The Tri-Sphere has the added benefit of simplicity of drilling layouts. Rest assured, keeping things workable and forgiving for both the driller and bowler is the ultimate goal. With its low RG, high differential shape, the Tri-Sphere will be a bowler’s best friend when the conditions are demanding.
