Solid Zone

Brunswick’s International Series has been developed specifically for Asian markets using core and coverstock systems that provide Asian bowlers with a range of equipment that matches up to typical Asian 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.
Reaction Characteristics
The Solid Zone uses a Brand New coverstockto the International Zone line called SuperKoil-7 and a proven Low RG core system to increase traction in the Mid lane and Backend on Heavy Oil lane conditions while preserving Maximum Forgiveness and Utility. We start with PowerKoiland mix in an aggressive additive to make the ball respond faster and you have SuperKoil,the most aggressive coverstockevery used in the International Zone line. The Solid Zone will be a favorite for bowlers looking for a Hooking ball that responds quickly in the mid-lane, with a strong continuous arc on the backend.
Response Time
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.
Utility
Out of the box: With its dull 1000-grit wet sand surface the Solid Zone matches up well on medium to oily lane conditions.
When shined: Using Brunswick’s Factory Finish High Gloss Polish or Rough Buff, the total hooking action of the Solid Zone can be reduced and the arc made more skid/snap. Both polishes reduce hooking action in the oil and increase reaction on dry back-ends. The Rough Buff provides a moderate amount of change and the High Gloss Polish a greater amount of change. To duplicate the Rough Buff Factory Finish start with 220-grit on the ball surface and apply the Rough Buff Polish. To duplicate the High Gloss Factory Finish start with 400-grit on the ball surface and apply the High Gloss Polish.
Reaction Setup
The Solid Zone can be drilled using the standard drilling techniques developed for two-piece balls, see the included drilling instructions for reaction characteristics and layout details.
