Columbia 300 Eruption

47.5 Hook 15.5 Length 15.5 Breakpoint Shape

Core Design: The conservatively shaped Resurgence symmetric core provides the power for this skid/flip edition. The low-RG 2.46 core starts up fast to help the rev-challenged. The medium .043 Diff supplies nearly 4.5” of maximum track flare with stronger pin distances. Our 5.5” test ball produced 3” of track flare with very tight flare rings, perfect for a long and strong breakpoint shape on light to medium volumes.

Coverstock: Ultra violet and electric blues compose the Eruption’s youthful appearance. The formula is called New Era Skid Flip and, as expected, provides very limited friction in oil, yet responds quickly when encountering drier areas. Factory finish is 2000 Abralon with factory high gloss polish.

Manufacturer’s Intent: “The Eruption is designed to be a medium to dry lane option and to complement the Burst and Outburst balls as they all use the same Resurgence Core,” says Columbia 300 Brand Manager Bugsy Kelly. “Using a New Era Skid Flip cover along with a low RG core creates a really unique back-end reaction.”

Test Results: With the success every ball with the Resurgence core has had, we figured we’d like the motion and hit of the Eruption. This core design is release-friendly as the ball maintains its motion shape with less than ideal releases on our part. The only sensitivity we saw was with the polished cover as it was somewhat wiggly when encountering oil carrydown. A light surface scuffing with a Scotch Brite pad solved this minor hiccup. On the other hand, bowlers with higher rev-to-speed ratios will be less affected by carrydown, and find no need to modify the finish.

When to Use: We had our best match-ups on light to medium volumes when length and a stronger back-end motion was required. When playing down-and-in, the Eruption busted loose too quickly in the friction, and the cover could not handle playing in the oil. When we bumped it in 2-4 boards, the Eruption came to life as it recovered quickly and decisively off friction. Our favorite layouts utilized pin distances between 4 and 5”, either above or below the fingers.
