Picking your champion requires more than weight alone. Consider factors like feeding behavior, age, and past performance.

Bears that fish early in the season often have an advantage, as they accumulate more fat reserves by October. Watch daily photos and note which contenders are visibly fuller over time.
Past Performance and Experience
Veteran bears like Otis benefit from past victories and prime access to feeding grounds. Newer contenders can surprise due to age and agility, so weigh each matchup carefully.
