It doesn't over-react, which makes it feel like it surpasses mid-price performance and steps into UMP (Upper Mid Performance), so you can use it when you feel the oil with the supple and stable movement of the 'Kinetic' core. For medium conditions, a polished solid coverstock might be more stable. If it's a strong solid material with a polished finish and a 'Kinetic Core', those who understand the performance will likely own this ball." ※The original box is not available, so it will be shipped in a substitute box. ※For the listing, simple oil extraction and surface regeneration treatment have been performed. #Bowling #Bowling #Ball #ABS #Ebonite #Hammer #Storm #Rotogrip #Brunswick #DV8 #Radical #Motiv #Track #900Global #Columbia300 #Radical #Ebonite #Storm #Rotogrip #Brunswick #Motiv #HighSports #LegendStar #columbia300 #Kinetic #Obsidian
