Translated from Japanese:
This time, the "Attention M" is a ball that sits between the Black Pearl, which gives a sharp edge on the back end, and the Attention S.
The "Momentus ™ Core" with a good rolling feel and the XtremeTrax+ ™ Pearl Reactive maintain rolling from the middle of the lane, showing a bend that looks like it is close to the pin.
It has high straight-line performance and shows smooth movement without losing power, so you can throw without worrying about rough lanes.
Even in the dry part, there is no need to use too much board width, so it is easy to take the throwing line and cause a powerful pin action.

Momentous Core
The NEW Momentous™ Core provides an entirely new philosophy for asymmetrical core motion for Roto Grip. By using new core density formulas the asymmetric imbalance now provides more downlane motion as well as more motion through the pins.
