Bowling's most popular brand name "Zone" is back on a new line of balls featuring asymmetric cores that incorporate an updated version of the Preferential Spin Axis Technology first developed and patented by Brunswick (US Patent # 5,074,553) in 1991.
Core
For 2007, Brunswick is bringing back an updated version of the bowling industry's original asymmetric core. The Phantom core was the first core with a two-pin design and a built in Preferential Spin Axis (PSA). The ABC/USBC used the Phantom core to establish the original RGmin and RGdiff specifications for the system of bowling. By using an updated version of the Phantom core, Brunswick has increased the asymmetric differential in the Zone line from 0.017” to 0.020”. Combined with Activator coverstock and a 800-grit wet sand finish, the Blast Zone upgrades the Strike Zone in the Zone Asymmetric line.
Drilling Note: Use the included drilling layouts or your current favorite asymmetric layouts for the Blast Zone. The original Phantom layouts are now obsolete and are not recommended.
Coverstock
The Blast Zone uses a hybrid version of Activator coverstock, combining the Activator Solid from the Ultimate Inferno® with the Activator Pearl from the Original Inferno. The Blast Zone retains the popular Activator ball reaction. Clean through the heads, but with an early revving type of roll, that promotes mid-lane recovery and a powerful but continuous breakpoint.
Reaction Characteristics
•Out of the Box: With its 800-grit wet sand surface, the Blast Zone is an ideal asymmetric ball on medium-to-oily lane conditions.
•If your Blast Zone goes too long: Dull the surface using 600-grit or rougher abrasive. 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.
•If your Blast Zone hooks too early: Smooth the surface with 1000, 2000 or 4000-grit abrasives to create more length. If your Blast Zone still hooks too early, polish the surface with either Brunswick's Factory Finish “High Gloss Polish” or “Rough Buff”. High Gloss Polish creates more length than Rough Buff.
