How Top Weight Affects Ball Motion - Creating the

2017-1-25  In this Creating The Difference blog we take a look at how top weight effects ball performance. Top weight is defined as the actual weight difference between the Bottom Half and the Top Half of the Bowling Ball. When a bowling ball is designed, the ideal top weight is around 3 ounces. This allows for the holes to be drilled into the bowling ball removing top weight so that
