The Blast Zone brings an updated version of bowling's first asymmetric core, the Phantom core. The Blast Zone is sure to blow your mind and Blast your competition.

For 2007, Brunswick is bringing back an updated version of the bowling industry…trade;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 RG-min and RG-diff specifications for the system of bowling. By using an updated version of the Phantom core, Brunswick has increased the asymmetric differential of 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.

The Blast Zone uses a hybrid version of Activator coverstock, combining the Activator Solid from the Ultimate Inferno¦reg; 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.

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…trade;s Factory Finish “High Gloss Polish” or “Rough Buff”. High Gloss Polish creates more length than Rough Buff.
