The Revolution Pro Winning Speed has been created for international bowlers and the lane conditions they typically encounter. The (Insert Coverstock Name) coverstock is finished with the new 4000 Sia Air finishing pads. The strength of the coverstock comes through on backend where it holds to the lane and creates a driving force through the pins. The Revolution Pro Winning Speed features a Low RG core that creates medium flare potential. This core, combined with the (Insert Coverstock Name) coverstock work together to create a ball that will be clean through the front part of the lane, with great response on the back part of the lane. The coverstock is very versatile and can be used over a wide variety of lane conditions by adjusting the surface of the ball. Bowlers will find this ball to be a great tool when the conditions require a strong backend reaction. The Revolution Pro Winning Speed can be drilled like other standard twopiece ball designs. With an RG Differential of 0.042 this ball has the potential to create a higher amount 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.
