heftiest
Weighing the most
Heftiest is the superlative of hefty—the heaviest, bulkiest, or most substantial of a group.
Physical objects can be heftiest: He grabbed the heftiest log for the fire.
The word extends to abstract weight: the heftiest price tag, the heftiest fine, the heftiest portion of the budget.
