Columbia 300: Disruption Hook 49 • Length 15.5 • Breakpoint Shape 15.5
Manufacturer’s Intent: “This is the first time New Era [coverstock] has been used in a completely solid form, and we discovered results that are sure to make the Disruption our best addition yet to the Eruption series,” says Columbia 300’s Bugsy Kelly. “The Disruption joins the Violent Eruption [July 2012], Mass Eruption [November 2012] and
Eruption [July 2011] in the Mid- Level Performance category.” Core Design: The Disruption’s symmetric core is familiar, to be sure — the proven Resurgence. The low RG of 2.46 creates fast revs, and the .046 differential produces nearly 5 inches of track flare.
Coverstock: The New Era solid reactive cover mirrors the quick response characteristics of the other balls in this series. Oil traction is limited, though, with the factory finish of 800-, 1000- and 2000-grit sandings, followed by high-gloss polish application. Colors are a mix of yellow and indigo. The effective surface grit measurement is 5400. The Ra reading is 1.6.
Test Results: Columbia’s Eruption series has long been known for its easy length and strong back- end motion. The Disruption adds yet another element to this series, now in a solid reactive
cover. Our favorite feature of the Disruption was its hitting and pin carry power. We were happy with the easy length and the smooth- yet-strong continuous arc at the finish, but the hitting power was memorable. This proves that when a great core and a proven cover
marry, the results can be spectacular. The Resurgence core once again proved to be very release-friendly. The New Era cover also is one of Columbia’s most well rounded in regard to mid-lane motion and friction response. When to Use: Because of the ball’s highly polished finish, the majority of my test staff had their best match-ups on medium and lighter oil volumes. The easy- revving nature of the core helped control the motion when leaving the oil pattern. Our balanced 50x4x50 dual angle layout, complements of the Blueprint software, was by far the most usable on both wet/ dry house shots and tougher, flat Sport shots. This layout, with light Abralon scuffing, even reacted well on some heavier test patterns.
“The Long Horn was
designed to complement the Stampede [October 2012], and uses the same core shape,” says Seismic Bowling Managing Director Ryan Press. “The cover is a pearl version of the
Stampede cover, and that, combined with raising the RG of the Horn core, gives the bowler a ball to move to when they want to get even deeper and open up the lane. The Long Horn will offer more length than the Stampede
and a more aggressive back-end motion than we have previously produced.” Core Design: The modified
asymmetric Horn core has a slightly higher RG of 2.53, lower differential of .045 and lower PSA of .017. These modifications help produce added length and less mid-lane hook. We saw an average of 4 inches of track flare with our 4- and 6-inch pin distance test balls.
Coverstock: The pearlized Stampede cover is called S.F. 9/8 reactive. The factory finish is a 2000-grit polish. Coloring is a vibrant blending of
bright denim blue and goldenrod. The
TIPS AND TRICKS TO MAKE YOU A BETTER BOWLER
Seismic: Long Horn Hook 53 • Length 16 • Breakpoint Shape 17
////////////////////////////////////////////////////////// ////////// Manufacturer’s Intent:
response time off friction is very quick and the traction in oil is limited. The Ra reading is 1.55, with an effective surface grit measurement of 5400.
Test Results: “Long and
strong” best describes the Seismic Long Horn. We’ve always enjoyed the back-end motion from the Horn core shape, and the Long Horn adds a few extra feet of length. The breakpoint motion shape is skid/flip, as the cover formula is very assertive off
friction areas of the lane. The core responds well to hand position changes for those toying with modifying their degree of axis rotation. The aggressive skid/flip nature of this cover can be subdued with sanding to 2000 grit or lower.
When to Use: Use on broken-down house or Sport oil patterns, as the ball is about length and flip. Stay away from heavy wet/dry oil patterns, as it was too weak when pulled into the oil and way too strong if sent to early friction. Blended patterns, on the other hand, were no match for the ball’s hitting and carry power. Our favorite skid/flip layout was a 70x4x35 dual angle. A slightly smoother breakpoint motion option can be obtained with a 60x6x40 layout.
