A month ago (actually 1 day before this bowling ball was released) there was a Demo Day at the House that I bowl on my one and only league. Out of all of the balls, the one I settled on was the Columbia 300 Impulse.

Like the Demo Ball, I had this ball drilled straight up dead nuts center. On of my team mates was telling me I should have changed where I drilled the ball, needless to say, I rolled a 289 with the Demo Ball, and I saw no reason for me to change anything.

This ball hits the pocket Hard, I mean really hard, the reaction it has on the pins is devastation like no other ball I have ever owned. I know I sound like an advertisement, but up until I purchased this ball my best League series was a 701, and now I have an 803 series.

By far my favorite ball in my bag.
