The intent of the new Rising Star was to create a ball that works well on medium-light oil patterns for bowlers with different skill levels and styles. With the benchmark-type symmetrical core shape, the original Dark Star was the cornerstone of the Shield line in 2010, and the new Rising Star will fit the same parameters and perform even better. The Rising Star was designed to increase total hook as compared with the Dark Star, the Ultimate Vision hybrid coverstock is a must for this new release. It creates a smooth glide through the heads with ample bite on the dry boards without being over-sensitive. And with a 1500-grit polished finish, the new Rising Star is sure to raise the bar. A journey to the center of the ball will reveal the new Neutron core as the power source. The Neutron core's medium RG-medium differential shape is based on the concept started with the original Photon core utilized in the Dark Star. But you'll find an even lower RG and higher differential in the heavier weights. So look for more motion out of the Rising Star with all the benefits of a hybrid coverstock. As you rise to the top with this new Roto Grip release, you'll quickly see why it earned the name Rising Star!

Ultimate Vision Hybrid Coverstock
Type
Hybrid Reactive

A first of its kind, the Ultimate Vision hybrid coverstock is 1 part solid and 2 parts pearlized reactive. This combination produces superior mid-lane read and pin shattering entry angle to the pocket.

Neutron Core

The Neutron™ core boasts a lower RG and higher differential when compared to the Photon™ core - this transforms into an earlier read and stronger backend reaction.

The late-rolling Neutron™ core is a model of consistency, producing good length and strong motion down-lane.
