| Walleye | 8-12 lb | 8-12 lb | 10-20 lb | 8-10 lb FC |
| Pike/Musky | 15-20 lb | 15-25 lb | 30-80 lb | Wire/Heavy FC |

How It Works
Line Types
- 1
Monofilament
Stretchy, floats, visible. Good for topwater and treble hooks.
- 2
Fluorocarbon
Low stretch, sinks, nearly invisible. Great for clear water and finesse.
- 3
Braid
No stretch, high sensitivity, visible. Best for heavy cover and long casts.
Pro Tips
Braid + Leader
Use braid mainline with fluorocarbon leader for sensitivity + invisibility. Our leader calculator helps you choose the right leader setup.
Match the Hatch
Lighter line in clear water, heavier in murky water or cover. See our line strength chart for species-specific recommendations.
Drag Setting
Set drag to 25% of line strength to prevent breakoffs. Pair your line with the right lure weight using our lure weight calculator.
Check Your Line
Inspect for nicks and abrasion. Replace line regularly. Use our fishing line guide for detailed line care tips.
Frequently Asked Questions
For general bass fishing, 12-15 lb fluorocarbon is a versatile starting point — it works for Texas rigs, jigs, and spinnerbaits. In heavy grass, use 30-50 lb braid for its weed-cutting ability and zero stretch. For finesse techniques like drop shot and Ned rig, 6-10 lb fluorocarbon or 10-15 lb braid with a 6-8 lb fluorocarbon leader works well. Use our leader calculator to set up the right braid-to-leader connection and our jig head weight calculator to pair the right jig with your line strength.
Fluorocarbon is nearly invisible, sinks, and has low stretch — best for clear water and finesse. Braid has zero stretch, high sensitivity, and thin diameter — best for heavy cover and long casts. Monofilament stretches, floats, and is visible — best for topwater and treble hooks. In clear water, use fluorocarbon or braid with fluorocarbon leader. In murky water or heavy grass, braid direct tie is fine. Check our line strength chart for a complete comparison and our lure fall rate calculator to see how line type affects sink speed.
Walleye: 6-8 lb braid with 6 lb fluorocarbon leader for sensitivity and invisibility. Pike/Musky: 30-80 lb braid with wire leader — bite protection is essential. Panfish: 4-6 lb monofilament or fluorocarbon. Smallmouth: 6-8 lb fluorocarbon in clear water. Match line to species size, cover, and water clarity. Our lure weight calculator can help you pair the right line with your lure weight, and our rod lure weight match calculator verifies your rod setup.
In clear water, use fluorocarbon (nearly invisible) or braid with fluorocarbon leader. In stained water, monofilament or fluorocarbon direct tie works. In murky water, braid direct tie is fine since fish can't see the line — the sensitivity helps you feel bites. The clearer the water, the more important line invisibility becomes. Use our leader calculator to determine when you need a leader and our lure color selector for color adjustments based on water clarity.
Yes. Braid has zero stretch — better sensitivity and hooksets but can rip hooks out of soft-mouthed fish. Fluorocarbon has low stretch and sinks, which affects crankbait depth and fall rate. Monofilament stretches, absorbs shock (good for treble hooks), and floats (good for topwater). Match line properties to your technique. Our lure fall rate calculator shows how line type affects sink speed, and our crankbait depth calculator shows how line type affects running depth.
