Roto Grip Critical Theory

The Triliptic core helps the ball get into a roll easier due to the additional contours and elongation of the ellipses within the shape of the weight block. With the Critical Theory, Storm is expanding the Theory series with its first pearl Insight coverstock. Designed to maximize dry lane traction, this shell will help increase your entry angle and sharpen your break point, all in an effort to help you strike more! Testing proved that the Critical Theory created the most entry angle in the entire product line. Its textured 4000-grit surface increases the Ra value, minimizes oil sensitivity, especially at the end of the oil pattern, and maximizes your bowling enjoyment. Wrap the new textured pearl Insight cover around the high-torque, asymmetrical Triliptic core and you have some horsepower.
