USBC rule modifies how bowling balls can be drilled; 2-year window to make adjustments

Balance holes will become illegal effective August 1, 2020. If you have any bowling balls with balance holes that you wish to use in USBC-sanctioned competition on or after that date, you must have the balance hole plugged. Starting August 1, 2018, balls that do not have balance holes (including balls with balance holes that have been plugged) are allowed to have up to 3 ounces of static imbalance in all directions (positive side/negative side, finger/thumb, and top/bottom).
From August 1, 2018 until July 31, 2020, balls that DO have balance holes are limited to the "old" static imbalance rules of 1 ounce for side weight, 1 ounce for finger or thumb weight, and 3 ounces for top or bottom weight.

This means that there is a two-year "phasing in" period giving bowlers time to adjust to the new rules. If you would like to, you can start drilling balls today that conform to the new rules (no balance holes, but with more weight imbalance allowed). You may also continue drilling balls that follow the old rules (with balance holes, BUT with the old, stricter static imbalance limits). Also, bowlers now have the option to start plugging their balance holes in preparation for the August 1, 2020 balance hole ban.
