With the benchmark-type symmetrical core shape, the original Roto Grip Dark Star™ was the cornerstone of the Shield line in 2010, and the new Roto Grip Rising Star will fit the same parameters and is reported to perform even better.
The intent with the new Roto Grip Rising Star is to increase total hook as compared with the Dark Star, using the “Ultimate Vision™ hybrid” coverstock (1500-grit polished). The new “Neutron™ core” “powers” the new entry. 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.
Roto reports “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.” This Roto Grip release is planned for February 16, 2011.
