Reaction Characteristics
Introducing Zone Pro-Tealâ„¢ Proactiveâ„¢ with (ETX 5) traction, the newest in the
Zone line and the latest Proactive coverstock innovation from Brunswick engineers.
The Zone Pro Teal is a higher “average RG” version of the Zone Pro Azure with a
similar “differential RG”. This change in mass distribution creates a Proactive ball that
pushes through the middle part of the lane with a straighter trajectory than the Zone Pro
Azure, than provides a more abrupt breakpoint.
The traction effect generated by Proactiveâ„¢, even when shined, generates a significant
increase in overall hook for virtually any bowler style on a wide variety of lane conditions.
If the bowler desires more hooking action out of the box, Proactiveâ„¢ can be sanded and
will provide a cleaner front end reaction than dull reactive balls, while increasing mid-lane
and back end reaction. Proactiveâ„¢ is a significant improvement over reactive urethane
technology when used dull and delivers a reaction that is much less sensitive on the front
part of the lane. Most of the increase in hook will come in the middle and backend parts of
the lane, offsetting any early reaction that may be created by sanding the ball.
