The Critical Theory was one of the most popular balls in Roto Grip history and it's back in a new form, the Roto Grip Critical bowling ball!
The Triliptic core that was made famous in the Theory line is back! This high flaring core provides a ball reaction that doesn't quit on the backend.
The new addition to the equation is the new 67MH Hybrid coverstock which is finished at 3000 grit with no polish, just like the Critical Theory. This new coverstock will mimic the strong, smooth roll on medium-heavy oil that the Critical Theory provided, only for today's conditions.
The Critical is the perfect combination of old and new which will deal a deadly accurate blow to the pins and the competition.
