Dv8: Brutal Nightmare Hook 53 • Length 15 • Breakpoint Shape 16

////////////////////////////////////////////////////////////////////////////// Manufacturer’s Intent:

“The Brutal Nightmare was developed to pro- vide strong hook motion with aggressive back-end reaction on medium to heavy oil,” says DV8’s Aaron Koch. “The Class 8 hybrid coverstock will get the ball farther down the lane

with a much more aggres- sive breakpoint than the original Nightmare [No- vember 2012]. The added length and quicker response

to friction provide more entry angle to the pocket and better continuation through the pins.”

Core Design: DV8’s Nightmare Low RG asymmetric core provides plenty of giddy-up for the Brutal Nightmare. The RG is medium-low at 2.50, the diff eren- tial strong at .052 and the PSA strength moderate at .013. Testing showed near- ly 6 inches of oil-loving fl are with strong layouts.

Coverstock: The Class 8 hybrid

coverstock is colored in shades of blue, orange and lime. The factory fi nish is sanded with 500 SiaAir and polished with Rough Buff and, lastly, high gloss. The responsiveness off friction is quick and strong, and oil traction is limited at

box fi nish. The Ra is 1.7. The surface grit is 5150.

Test Results: The Brutal Night- mare will be a perfect step down for those using the heavier hook- ing Nightmare solid. They share the same fast-revving, high-fl aring core, so pay attention to layout choice to control track fl are and motion shape. The Brutal Night- mare will clear the fronts and midlane slightly easier, plus pro- vide a more angular breakpoint shape when leaving the oil pattern. On wet/dry patterns, we needed to play well inside the oil line to lessen the move off friction, yet we still saw above-av- erage carry if we paid attention to ball speed. On fl atter Sport-type patterns, we had good looks when playing inside lines as the ball provided lots of recovery.

When to Use: With the strong cover and aggressive asymmetric core, one would think the only match-ups would be on medium-heavy fresh patterns. We also en- joyed some of our best pin carry on beat- en-up house patterns when playing well inside. The combination of the cover and core gave us easy length and an aggres- sive hard arc from our deep-inside launch angles. Our favorite layouts incorporated higher drill-to-VAL angles to create a hock- ey stick shape.


Dv8: Diva Hook 49 • Length 16 • Breakpoint Shape 16

////////////////////////////////////////////////////////////////////////////// Manufacturer’s Intent:

“For the Diva, we targeted an all-purpose ball motion with strong backend,” says DV8’s Aaron Koch. “With the

Class 6G cover and the new Diva core, the Diva skids through the front and midlane, revs hard on the backend and then fi nishes strongly through the pin deck. The Diva will play on a wide variety of lane conditions for many diff erent styles of bowlers.”

Core Design: The Diva symmetric core has a medium RG of 2.51 and a healthy .052 diff erential. Strong drilling layouts should produce nearly 5.5 inches of track fl are for those looking for added total hook. The conservative shape was both release-friendly and very continuous through the pin deck. Coverstock: The Diva has a pink and black color scheme. The factory fi nish on the Class 6G cover is sanded with 500 SiaAir, Rough Buff fi nished and then high-gloss polished. Response time off friction is moderately quick and oil traction is limited. The Ra is 1.5 and the surface grit measures 5450, great for lighter oil patterns.

Test Results: The Diva expands the motion range from DV8 in its upper mid-priced segment. The stronger formula cover (6G) increases overall hookability compared to the Class 3 covers of the Reckless (September 2011) and Too Reckless (December 2011) balls. The Diva clears the front easily and makes a strong, hard arc in the fi nal 20 feet. I’d classify the motion as skid/fl ip on fresh medium volumes to skid/strong arc through transitioned patterns. Overall roll and hitting power were

very good on blended patterns for all tes- ters. On fresh house patterns with higher ratios, we noticed moderate over-under characteristics. A light surface scuff solved this minor annoyance, as it usually does. When to Use: The Diva will come to play on most light to medium volumes of either Sport or house patterns. We felt we had our best looks on Sport with the Diva at box fi nish (high polished). With a light scuff ed fi nish and at 4000, the Diva gave us added targeting room and better pin carry on our house shot test patterns, which were oiled with 8-to-1 side-to- side ratios of 25-ml. oil volume at 41 feet. The three DV8s tested this month would make a great 1-2-3 punch in anyone’s arsenal.
