This pearl version of the original Tremendous adds more length and more flip compared to the original Tremendous. The Tremendous Pearl also features a new resin formulation, Radical calls it Ai30. Ai stands for Additive Index, 30 is the level of additive they used.
The Tremendous Pearl will give you all the features of the Tremendous (using the original Guru core) just further down the lane and quicker off the spot with the same continuation the bowlers rave about in the Tremendous.
