The NEW cover "Power Traction S" solid cover has a tenacious grip on oil, guiding the ball to the backend, and explosively unleashing the potential of the Iron Cross core, creating a good pin action. The fusion of "Iron Cross core" and "Power Traction S" provides a good balance of friction control and backend snap, stabilizing the entry angle before the pins and generating explosive pin carry. ※The original box is not available, so it will be shipped in a substitute box. ※For this listing, simple oil extraction and surface regeneration processing have been performed. #Bowling #Ball #ABS #Ebonite #Hammer #Storm #Rotogrip #Brunswick #DV8 #Radical #Motiv #Track #900Global #Columbia300 #Radical #Ebonite #Storm #Rotogrip #Brunswick #Motiv #Hi-Sports #Legend Star #columbia300 #Perfection
