The term "overbalanced" means that something is not in equilibrium, and is leaning too far in one direction. The antonyms for this term could convey the opposite meaning such as balanced, stable, symmetrical, or equalized. A balanced object is poised and stable, indicating that it is neither tipping nor falling. Likewise, a symmetrical object has a similar shape, size, and arrangement on either side of its axis, rendering it balanced. Equalized means something that is adjusted and made similar or even, indicating a balance. All of these antonyms suggest that the weight is distributed evenly, providing a sense of stability and equilibrium that "more overbalanced" lacks.
