The Revolution Speed Star has been created for international bowlers and the lane conditions they typically encounter. The Revolution Speed Star features a high density inner core that creates a Low RG ball with a medium differential RG that allows the ball to roll heavy through the midlane but still be aggressive in the backend. The PowrKoil 18 coverstock combined with the medium differential core combination used on the Revolution Speed Star helps the ball stay on line through the front part of the lane and then respond aggressively in the midlane and backend. This core and coverstock combination work together to create a ball that rolls strong over the entire length of the lane while still being very versatile and can be used on dry to mediumoily lane conditions to provide superior reactions. The PowrKoil 18 coverstock is finished with Rough Buff 1500 Grit Polish. The Revolution Speed Star can be drilled like other standard twopiece ball designs. With an RG Differential of 0.042 this ball has the potential to create medium amounts of track flare for most bowlers. Bowlers with average physical games can use stronger leverage type layouts to get good reaction on medium conditions and label type layouts on drier lanes. Bowlers with stronger physical games can also use leverage layouts on mediumdry conditions and label type layouts with the pin above the fingers to get the ball down the lane while maintaining a strong backend reaction on drier lane conditions.
