From the manufacturer

Formulated for ALL bowlers regardless of their style or their skill level. The latest installment in the RST Series provides WAY more mid-lane motion than the RST X-2, while still providing PLENTY of giddy up down lane. This version of MicroTrax™ Hybrid features nano particles throughout to provide the traction you need in oil, while its two parts pearl provide you the reaction you have come to know and love about the RST Series. So, whether you are a recent PBA Hall of Famer, or this is your very first high-end ball, the RST X-3 will provide unparalleled reaction time and time again.
