A 5-weight rod would snap moments after you set the hook on a summer steelhead. A 3-weight could not even pretend to cast muskellunge flies. And while a 9-weight might cause your backpacking friends to question such a heavy rod…you know better. If you chase big fish (Northern Pike in the Boundary Waters, Summer Steelheads in the Cascades, or Roosterfish in Costa Rica) you need a rod that can handle your quests. And besides, would you rather carry five boxes of Mac ‘n Cheese, or one measly fishing rod?
