The Violent Eruption is the newest mid-priced performance ball for the Columbia 300 brand. This ball joins the successful Eruption from last season at this price point. This new addition uses the same core shape as the Eruption, but with some very minor density changes. The biggest change is the different coverstock, named New Era SF Plus. For our test staff, the Violent Eruption started up just a tad sooner than the Eruption, but with a bigger and stronger move downlane.

Our testers by far had their best reaction on our medium test pattern. That is saying something considering we made no surface adjustments on any test pattern for the entire testing session. Stroker and Cranker had impressive reactions. Stroker was going straighter and could notice the change of direction downlane. Cranker really liked throwing this ball as well.

Performance Ratings

Name	Value	Comments
Torque (1-10)	7.5	The Violent Eruption is equipped with a new coverstock called New Era SF Plus. This coverstock is even stronger at the breakpoint than the first Eruption.
Length (1-25)	13	We found this ball to start up just a little sooner than the first Eruption. The slightly earlier read sets it up for a big back end move.
Back End (1-20)	17	The Violent Eruption covers a lot of area in the last part of the lane. All three testers had unbelievable recovery on our medium test pattern.
Total Hook (1-100)	50	The increased back end motion gives the Violent Eruption more overall hook than the Eruption. This strong pearl gives bowlers another pearl option between the Eruption and the Encounter.

Strengths: The ability of this ball to create enough traction in the midlane while still storing energy for an explosive move at the breakpoint and back end is something we have not seen in a while, especially from a ball that is not a high performance release.

Weaknesses: There are very few weaknesses for the Violent Eruption. Only the extremes of oil patterns will keep this ball in the bag.

Overall Summary: This ball was simply unstoppable in our testers' hands on our medium pattern. Any type of medium pattern will put the Violent Eruption in play.
