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.
