Bowlers still can have a bowling ball with a balance hole until Aug. 1, 2020, but any balls with a balance hole must stay within the current static weight specification of one ounce for finger, thumb or side weight, and three ounces for top or bottom weight.
The specification eliminating the use of balance holes still will go into effect Aug. 1, 2020.
“After hearing from all stakeholders, the committee decided it was the right move to make the static weight specification an option starting this fall,” Andrew Cain, chair of the USBC Equipment and Specifications Committee, said. “Bowlers now have a two-year window to work with their pro shops to ensure their equipment will meet specifications on Aug. 1, 2020.”
With the elimination of balance holes as of Aug. 1, 2020, bowlers may have up to five holes for gripping purposes and all gripping holes must be used on every delivery. A bowler who chooses not to use a thumb hole would need to mark by scribe, engraver or tool their intended center of palm with a plus (+) mark to indicate their grip orientation.
