Dv8: Ruckus Hook 55 • Length 14 • Breakpoint Shape 16

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

“We targeted the Ruckus to be the strongest skid/ flip ball in the DV8 product line,” says DV8 R&D engineer Aaron Koch. “The new Class 8F hybrid cover, along with the new core shape, allow the Ruckus to skid easily downlane before making a stronger move off the spot than previous DV8 products.” Core Design: The skull- shaped asymmetric core boasts a medium RG of 2.54. The differential is .052 and the PSA is .013. Testing showed 5.5 inches of track flare with strong 4-inch pin distance layouts. This core design’s simplicity and effectiveness have been proven for many years. We saw release forgiveness and consistent continuation on most patterns.

Coverstock: The Class 8F cover is a hybrid type, colored in blue, black and lime hues. The factory finish is sanded with a 500-grit pad and polished with Royal compound to a satin-sheen finish. Response time is quick, and oil traction

is moderate. The measured Ra is 3.0 with a 4300 effective surface grit. Test Results: The Ruckus may cause a ruckus for anyone who can play only direct lines to the pocket. I say this because the quick-response cover lends itself to playing more open launch angles from inside lines of attack. After plugging a test ball to a 40x6.25x65 layout, we found that a weak drilling is your only option to be able to play down and in. The rest of us will enjoy the

ball’s ability to open up the lane with its aggressive back-end motion. The 8F hybrid cover brings versatility and usefulness on many medium-heavy oil volume patterns for all player styles. When to Use: With stronger layouts, players will easily be able to play well inside the oil line and swing-it and bring-it. The Ruckus is built for many fresh patterns where a bowler needs adequate mid-lane traction but wants an aggressive move downlane. The DV8 lineup provides an array of hook potential and motion shapes, but the majority tend to “bust a move” in the final 20 feet — including this one.


Dv8: Dude Hook 48 • Length 16.5 • Breakpoint Shape 15.5

////////////////////////////////////////////////////////// //////////

Manufacturer’s Intent: “The Dude was designed to be an extremely versatile piece at the center of the DV8 line,” says Aaron Koch. “The new Class 4F reactive coverstock, along with adjusting the dynamics of the Diva core, produces a motion which glides through the fronts and mids with a strong flip on the backend. The Dude will be the first ball out of the bag for many bowlers.” Core Design: The Dude’s symmetric core has a medium RG of 2.55 with a .040 differential. There was up to 4.5 inches of track flare measured during testing. This core helps the Dude create length and a strong back-end arc. Coverstock: The Dude features the Class 4F solid reactive formula, colored in black and purple hues. The factory finish is sanded with a 500- grit pad, followed by Royal compound and then Royal Shine. The response time is moderately quick off dry, and somewhat limited in oil. The Ra measures 2.1 with an effective surface grit of 4900. Test Results: The Dude sports a different cover and core than its sibling

Diva (February 2013). Even though the core has less flare potential and the cover is slightly weaker, the hitting and carry power remain strong. In fact, when compared to a like-drilled Diva, the Dude had an average of 1.5 feet added length and one to two boards less total hook. We felt the core and cover matched each other nicely, as small release errors and targeting misses were hidden, especially on light to light-medium oil volumes. The Dude never displayed a skid/flip motion shape on any of our test patterns; it was more of a hard-arcing motion. When to Use: The Dude abided best on broken-down THS and lighter Sport- type patterns after a defined hook spot developed. This environment allowed us ample recovery downlane and great hitting power. If we used the Dude on medium-heavy volumes, the mid-lane read was often too late, with insufficient back-end motion. We actually had great reaction and carry with either our pin-above or below layouts on lighter volumes. Our pin positioned above at 4.5 inches displayed more angularity and worked best playing inside lines. Our pin below the fingers made it easier to play more direct lines from 13-board and out.
