The Revolution Rebel Egoist Black has been created for international bowlers and the lane conditions they typically encounter. The new Supreme Strength coverstock with rough buff polish, creates a strong grip to the lane. The gripping strength of the coverstock comes through on back-end where it holds to the lane and creates a driving force through the pins. The Revolution Rebel Egoist Black uses a core system which incorporates high and low density fillers to create an optimum medium RG match-up for length and angularity. The core’s medium RG helps push the ball through the front part of the lane. The core and coverstock combination work together to create a ball that is very versatile and helps smooth over reactions to the driest part of the lane, creating a smoother, yet predictable ball reaction. The Revolution Rebel Egoist Black can be drilled like other standard twopiece ball designs. With an RG Differential of 0.024 this ball will create a medium 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.
