TRIPLE XTREMEBall Line Master LineStorm Bowling has taken the Triple X Factor to the Xtreme... the Triple XTREME that is! This ball generates a massive amount of torque and will make the corner on even the toughest of conditions. This is accomplished by combining Storm Bowling's world class ACCU tread solid reactive coverstock, preparing it to an 800 grit satin finish, then wrapping it around the dynamic RAD3 weight block. The satin ACCU tread builds higher friction in the mid lane. The RAD3 creates a strong preferred spin axis that in tandem, make the Triple XTREME really lean toward the pocket. If you take your game seriously and want that edge, then take your game to the XTREME! Product Type Bowling Balls
