Complementing the Reax Version 2, the Pearl version gives just the right amount of additional length with an even stronger backend reaction. This difference allows bowlers to easily switch from the original Reax Version 2 to the Pearl when the lanes transition or when more entry angle is needed. The Reax Version 2 Pearl incorporates the innovative finger scoop core technology that provides a variety of advanced drillings in order to assure the desired performance. This combination of cover and core provides more length, more backend reaction and a greater entry angle resulting in MORE STRIKES!!!!
