Roto Grip: Disturbed

Manufacturer’s Intent: “For some time we have discussed the idea of a lower RG symmetrical core for the Roto Grip brand,” says Roto Grip’s Chris Schlemer. “That has now come to fruition with the Middle Roll 70 weight block. Coupling the new weight block with the 66MH solid reactive coverstock, the Disturbed means business on medium to heavy oil conditions. This ball now anchors the HP3 line, and will create motion in the midlane that Roto Grip fans have not seen in a long while.”

Core Design: The Middle Roll 70 symmetric core is all about rolling early and smoothly. The RG is reasonably low at 2.50 and the .043 differential will produce nearly 5 inches of oil-loving track flare. The new design was easy to rev and rewarded us with very good carry on less-than-perfect releases.

Coverstock: Supplying the needed lane traction is the solid 66MH reactive cover, which is factory finished at a 2000 dull grit. Colors are a fun lime green and black mix with neon yellow lettering. Oil traction is above average and response off friction is moderately quick, yet strong. The measured Ra is 7.5. The surface grit is 3000.
Test Results: Some balls, like the Disturbed, create a visual motion down the lane that just looks impressive and powerful. We saw very quick revs right off the hand for all testers and a strong, continuous down-lane breakpoint motion. The new core shape and low RG were major contributing factors to this reaction. In regard to hook, the Disturbed read the midlane earlier than a like-drilled Berserk (September 2012) and hooked a few boards more on average. We tried throwing the Disturbed through the breakpoint, but its strong core and 2000-grit solid cover would not allow it. It’s possible that Osku Palermaa, with his 22-mph-plus ball speed could.

When to Use: The Disturbed will match up well for speed-dominant players and those bowling on heavier volume oil patterns. The fact that it’s not a premium-priced product does not diminish any of this ball’s attributes. It just loves oil. Most players can easily play in the oil pattern and fire away; there is little need to send it near friction areas to create entry angle.
