Opsin Big Game 130 lb Fluorocarbon Leader
1.06 mm Ā· 30 m and 110 m
At 1.06 mm, Opsin 130 lb gives you more pull and abrasion margin than 100 lb without loading the bait down with unnecessary leader. Slow-extruded in Japan for a clean, consistent profile that stays manageable at the bench and dependable when the fish settles into the fight.
More pull. Still supple. Still built to let the bait work.
Rigging note: Match sleeve and crimp cavity to the measured 1.06 mm diameter. Start by bench-testing a Diamond Aluminum Silver Lock L sleeve at 1.3 mm, then pull-test the complete system before fishing.
UV-blocking metallized bagProtects the coil from light exposure and storage abuse.

The material
Strength without unnecessary bulk
130 lb is where a lot of serious tuna fishing gets done. The slow Japanese extrusion keeps the 1.06 mm profile clean and consistent, giving you more abrasion margin than 100 lb without turning the leader into cable.
It stays manageable at the bench, seats predictably in the right sleeve, and still lets a live bait work the way it is supposed to.
Thin by design
Less unnecessary bulk in the leader, with serious big-game capability.
Supple where it counts
Lets live bait move naturally instead of dragging a stiff leader through the water.
Built for clean rigging
Consistent diameter supports repeatable sleeve selection and crimp setup.
Field proof
Built for the part of the fight that matters
The bite is only the start. What matters is how the leader behaves after the fish turns, the drag settles in, and every connection has to keep doing its job.
Where 130 lb fits
Choose the leader for the job
130 lb is the clean step between finesse and heavy pressure: more abrasion margin and room to pull than 100 lb, while the 1.06 mm profile still presents a bait naturally.
| Line class | Diameter | Best for |
|---|---|---|
| 100 lb | 0.93 mm | The thinnest Big Game profile for natural bait presentation and lighter drag |
| 130 lbYou are here | 1.06 mm | Finesse-minded heavy tackle and cleaner bait presentation |
| 150 lb | 1.18 mm | Heavy tuna and versatile big-game rigging |
| 170 lb | 1.28 mm | More abrasion margin and higher-drag applications |
| 200 lb | 1.44 mm | Heavy drag, bigger hardware, and more insurance when the leader gets rubbed |
| 250 lb | 1.57 mm | Heavy leader work where abrasion margin matters more than finesse |
| 300 lb | 1.84 mm | Maximum leader class for the heaviest tackle and highest-abrasion rigging |

āUse Opsin from 2 to 180 lb. Trout to tuna. Works great, holds, stealth and gets bites when the bites are hard to come by.ā

What sleeve should I use with Opsin 130 lb?
Size the sleeve to the measured diameter, not the pound-test. Opsin 130 lb is 1.06 mm. Diamondās published guide places its Aluminum Silver Lock L sleeve at 1.3 mm for 0.95ā1.3 mm mono or fluorocarbon with the Mini-Press and CN-10 tools.
Use that as the first documented bench test. The sleeve should thread without shaving the leader and should not feel sloppy before compression. Match it to the manufacturerās cavity and pull-test the finished leader.
Diamond Silver Lock L Ā· 1.3 mm
Diamond publishes the L sleeve for 0.95ā1.3 mm mono or fluorocarbon with its Mini-Press and CN-10 guides. At 1.06 mm, it is the cleanest documented starting point.
Alternate 1.3 mm aluminum oval
Only use an alternate sleeve when its manufacturer publishes a diameter range that covers 1.06 mm. Match the cavity, reset pressure, and pull-test it as its own system.
Deckhand note: A sleeve that works on another brandās 130 lb may not fit 1.06 mm Opsin the same way. Thread it cleanly, keep the sleeve ends clear, reset the tool for the exact combination, and test the rig you plan to fish.
Should I choose 30 m or 110 m?
The 30 m coil is the clean choice for a trip bag or a handful of leaders. The 110 m crew coil drops the cost per metre and makes sense when you rig often, carry backups, or prep for a full season.
How should I store the coil?
Keep it clean, dry, and out of prolonged light and heat. Return the coil to the UV-blocking metallized bag between trips and avoid kinking it under hard tackle.
