What the solver builds around it

The most common pick at each other stage, across the 71 builds around the Trilene XL Monofilament 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 Berkley Trilene XL Monofilament. "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.

Where it falls short

The checks the Trilene XL Monofilament 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 under the fish’s windowwarn in 7 builds

    Muskellunge, Weedy Lake: 30 lb is light for Muskellunge. The working window for Muskellunge is 50–100 lb. You can land one on less, but every snag, every headshake, and every bit of structure becomes a coin flip.

    Mainline under the bottom of the fish’s line window gets a warning. You can land one on less, but every snag and headshake becomes a coin flip.

  • Leader heavier than the mainlinewarn in 3 builds

    Muskellunge, Weedy Lake: 135 lb leader on 30 lb mainline. Now the mainline is the fuse, which means a snag costs you the leader, the terminal tackle, and however much mainline was past the break. The leader is also thick enough to be visible and to stiffen your bait's action.

    Past 2x the mainline test the mainline becomes the fuse, and a snag costs the whole terminal end. The engine warns.

  • Reel line capacitywarn in 1 build

    Striped Bass, Inshore Flat: Reel holds ~240 yd of this line; Striped Bass wants 300+. The Daiwa BG MQ Spinning Reel is rated 240 yd of 20 lb mono (0.46 mm). Your 20 lb mono runs 0.46 mm, which works out to roughly 240 yd on the same spool. A fish that runs further than your spool holds breaks off at the arbor knot, every time.

    The reel’s rated capacity is scaled by line diameter to the line actually spooled, and checked against the yards the fish can take on a run, which climbs with the fish’s top weight. Short of it, the engine warns.

  • No leader against an abrasive fishwarn in 1 build

    Yellowfin Tuna, Offshore Bluewater: No leader against an abrasive Yellowfin Tuna. Yellowfin Tuna rates 0.60 for abrasion: gill plates, teeth, or the structure it lives in. Braid has almost no abrasion resistance; a 20-inch fluorocarbon leader at 80–174 lb costs pennies and stops most of these losses.

    Fish rated 0.6 or more for abrasion (gill plates, teeth, or the structure they live in) get a warning with no leader at all.

What fish is the Berkley Trilene XL Monofilament good for?

Built around it, the engine clears every check for Largemouth Bass, Smallmouth Bass, Rainbow Trout, Brook Trout, Walleye, Northern Pike, Channel Catfish, Blue Catfish, Crappie, Bluegill & Panfish, Common Carp, Striped Bass, Redfish, Speckled Trout, Snook, Flounder, Bonefish, King Mackerel, Salmon (Coho / King), and Steelhead. It works with warnings for Muskellunge.

What test of Trilene XL Monofilament should I use?

Across its clean builds the solver runs it from 4 lb to 30 lb. The table on this page lists the exact test for each fish and water; the window comes from each fish's line requirement and the rod it is paired with.

What does the Trilene XL Monofilament pair with?

Building around it, the solver most often picks the Eagle Claw Lazer Sharp Circle Sea (hook, 42 of 71 builds), the Yo-Zuri HD Carbon Fluorocarbon Leader (leader, 31 of 71 builds), the Okuma Ceymar Spinning Reel (reel, 29 of 71 builds), and the Ugly Stik GX2 Spinning Rod (rod, 28 of 71 builds).

Where does the Trilene XL Monofilament fall short?

line under the fish’s window (a warning in 7 builds, e.g. Muskellunge, Weedy Lake: 30 lb is light for Muskellunge), leader heavier than the mainline (a warning in 3 builds, e.g. Muskellunge, Weedy Lake: 135 lb leader on 30 lb mainline), and reel line capacity (a warning in 1 build, e.g. Striped Bass, Inshore Flat: Reel holds ~240 yd of this line; Striped Bass wants 300+).

How does it compare with other mainline options?

It ranks 7 of 8 mainline options in our catalog by clean builds (60 of 75). Prices are street-price estimates, not live Amazon prices.
