Columbia 300 Violent Eruption Bowling Ball

The first Violent Eruption I drilled has a 4 ½” Pin x 45 Degree Core Angle (Pin Down). This is my favorite layout on symmetrical bowling balls and the exact layout I used on my Original Eruption. Compared to the Eruption it reads the lane a hair later but has about 4 to 6 boards more hook on the backend, with the same great continuation through the pins like the original Eruption! This is my new favorite out on the Market! When Bowling this Month gave this a 10 rating they weren’t lying very versatile both polished and sanded, this is my go to ball. The second Violent Eruption I drilled is a 60* x 5 x 60* at 1000 Abralon. This ball is earlier than my Eruption and first Violent Eruption and covers 2-3 more boards than my first one with the same great backend and finish. I typically use this one when I need a earlier roll but similar motion as my go to ball. Great example how you can use a 1000 grit or a polished Violent Eruption and still get great continuation down lane. My Specs: Ball Speed: 17.5 MPH Rev Rate: 300 RPM Axis Rotation Angle: 45* Axis Tilt: 10* PAP: Over 4, Up 3/8 Average: 232
