i have never had a ball that hit the pocket this hard in my dreams. First four games out of the box i had 1 ten pin and my average was 20 pins higher with no games under average. the only thing is that you have to have the ball layed out by a driller that knowns what he is doing. so he has to watch you bowl first and find out your axis rotation, rev rate, .......ect. Also he may have to tweek the ball after drilling by fixing the weight hole. all this has to be done because the core wieghs 5.5 pounds which is more than double most cores on the market today.
