Technology
The Ultra Zone brings the new EnMotion reactive coverstock from the Twisted Fury into the Zone line and combines it with the updated Phantom core to create an ultra-low-RG alternative that complements the reaction of the Twisted Fury.

The Ultra Zone uses a Solid / Pearl Hybrid version of the EnMotion coverstock. EnMotion combines the best elements from our PowerKoil, Activator and N’Control coverstock systems to create good length combined with excellent mid-lane recovery and strong back-end hooking action. The Ultra Zone unites EnMotion coverstock with the ultra-low-RG updated Phantom core. Ultra-low-RG’s are known for strong mid-lane recovery moves and their controllable back-end hooking action, Brunswick has created an "mid-lane recovery" counterpart to the Twisted Fury that will match-up better on lane patterns that create over/under reaction problems for skid/snap balls.

Reaction Characteristics
•Out of the Box: With its Rough Buff finish, the Ultra Zone is an ideal asymmetric ball on medium-to-oily lane conditions.
•If your Ultra Zone goes too long: Dull the surface using 1000-grit or rougher abrasive. The hooking action will increase and its arc will become more even, creating a better match-up for heavily oiled lane conditions and for smoothing over/under reactions seen on wet/dry lane conditions.
•If your Ultra Zone hooks too early: Polish the surface with Brunswick’s Factory Finish “High Gloss Polish” to create additional length. 4000-grit surfaces, such as Scotch-Brite White pad or Abralon-4000 will also create additional length.
