What job does this tackle have to do?
One chain.
The weakest supported link
decides.
Start with the job — the water, the fish, the flow, the landing problem — then work backward through rod, reel, line, leader, connection and presentation. Declared ratings govern. Heuristics stay labelled. Missing specifications stay unknown.
Local-first · no locations collected · educational evaluation only
River
Current load, precision, abrasion, landing in flow
Lake
Depth change, vegetation, wind, search vs static
Ocean · Inshore
Salt corrosion, tide, structure abrasion, stronger fish
Deep-sea · Offshore
Continuous drag, capacity, depth, big-game loads
