From Brunswick:
ACTIVATOR PLUS Coverstock
The Diamondback Pearl â„¢ is the first ball with Activator Plus coverstock available at the Advanced Performance price point. The Activator Plus coverstock used on the Diamondback Pearl is a proven formula that provides strong mid and down-lane recovery, longevity of ball reaction, and unprecedented durability with superior resistance to cracking.
ROCKET Core
The Diamondback Pearl uses the proven Brunswick multi-sided Rocketâ„¢ core system. The Rocket core is a low RG core that aids the Activator Plus in mid-lane grip and back-end recovery.
Ball Motion
The Diamondback Pearl, finished at 4,000 Siaair Micro Pad, will provide excellent length through the front part of the lane. The core and coverstock strength give the Diamondback Pearl the potential for a strong, continuous backend reaction with remarkable pin action, on typical medium to oily lane conditions.
Reaction Setup
The Diamondback Pearl can be drilled using the standard drilling techniques developed for symmetric bowling balls.
