The Alert introduces a new symmetrical core design to the Brunswick lineup. The Alert core is a low RG (2.478″) and low differential (0.037″) design that revs up earlier and flares less than any recent Brunswick core, with the exception of the Vintage Light Bulb design that was used in the Ivory Rhino Pro.

Its dull, aggressive coverstock was just a little better for us on the heavy oil pattern, but it was still very good on the medium oil pattern as well.

He was very impressed with how well the ball continued to make the same motion as the pattern transitioned. In a normal league night in houses that have a slicker house shot, he would be
