Brunswick Bowling Balls.

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.Reaction CharacteristicsThe Dry Zone was designed especially for High Hooking Lane Conditions, Bowlers with High Rev Rates and Bowlers with Slow Ball Speeds. We start by using a newly redesigned Box Core shape with a medium RG rating and then incase the core with Reactive ⢠5 coverstock. This combination of a Low Flare Potential core system and Brunswickâ¦trades Most Forgiving Low Friction coverstock will make the Dry Zone the ball of choice for many bowlers who encounter High Hooking lane conditions and Short Oil Patterns. Response TimeTo 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 SkidSnap. The Lower the number the Slower the ball will change direction similar to Smooth Arc.UtilityOut of the box With itâ¦trades high gloss surface most players will find the Dry Zone matches up well on medium to 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 overunder reactions seen on wetdry lane conditions.
