The Bionic Zone 1 is a higher RG version of the Smart Zone 1. The Bionic Zone 1 uses the Smart Zone 1's SS Extreme Reactive coverstock but combines it with a higher RG inverted bell shaped core to save more hooking action for the back-ends. This core/coverstock combination creates a skid.snap reaction that matches up on medium-dry to medium-oily lane conditions, shorter patterns or broken down lane conditions. Bowlers with slower ball speeds or any bowler who has problems with the ball hooking early should appreciate the ball reaction of the Bionic Zone 1.
