All i know is Jaros made me want to buy this ball soon, hits like a tank the solid 8 pin kept from repeating on a super tough pattern. I have to stay off the ball buying binge for about 3 months, good thing i stocked up with a few nib's to drill once in awhile to give me a fix. I know that at some point i will buy this ball and maybe something else Dyno releases at bowl expo.
