What the solver builds around it

The most common pick at each other stage, across the 71 builds around the J-Braid Grand x8 that clear without an error.

Every fish, every water

Each row is the best rig the solver can build for that fish in that water while being forced to use the Daiwa J-Braid Grand x8. "Adds" lists the engine problems it brings that the free solve for the same pair does not have, and the last price column is the cost against that free solve.

Fish-and-water pairs are the ones we publish solved rigs for: water type matches and the fish is actually targeted there. Build prices are street-price estimates from our catalog.

Where it falls short

The checks the J-Braid Grand x8 trips that the free solve for the same pair does not, by how many builds each one fires in. The quoted line is the engine's own message from the first build it fired in.

Line heavier than the fish needswarn in 2 builds
Brook Trout, Mountain Creek: 10 lb is heavy for Brook Trout. 6 lb covers this fish. Heavier line is thicker line: it casts shorter, sinks slower, and is more visible. You are paying a presentation cost for strength you will not use.
Mainline past 1.5x the top of the fish’s line window kills the light presentation this rig exists for. The engine warns.
