Brunswicks International Series has been developed specifically for Asian markets using core and coverstock systems that provide international bowlers with a range of equipment that matches up to typical international lane conditions. The looks of International Series balls are also adapted to Asian tastes making the International Series completely customized for Asian bowlers. Available only through International Distributors.
The Racing Zone combines a High Gloss Activator pearl coverstock with the Ultra-Low-RG Asymmetrical core system to produce a ball reaction that will give the bowler Maximum Forgiveness and Maximum Backend.
To understand the International Zone Coverstocks better we will be using a 1-10 number scale system after the coverstock name to describe Response Time. Response Time is how fast or slow the ball changes direction when it encounters friction. The Higher the number the Faster the ball will change direction similar to Skid/Snap. The Lower the number the Slower the ball will change direction similar to Smooth Arc.
Out of the Box: With it's high gloss surface most players will find the Racing Zone matches up well on medium-oily to medium-dry lane conditions.
When dulled: The hooking action will increase and its arc will become more even, creating a better match-up for oily lane conditions and for smoothing over/under reactions seen on wet/dry lane conditions.
There are additional layout considerations for a ball with significant Preferential Spin Axis (PSA) such as the Racing Zone. The distance from the riser pin still determines the overall strength of the layout the same way it does in symmetric core balls that have an insignificant PSA. In the Racing Zone, placement of the PSA locator relative to the riser pin and the bowler's axis can be used to modify the reaction created by a given riser pin position.
