Leader Lines

Fluorocarbon Leader Line Buyer's Guide

The fluorocarbon leader lines on this page range from fine 7lb line for clear-water trout fishing through to a substantially stronger 31.28lb option for coastal fishing around rocks, weed and other abrasive structure. All five come on 120m spools and use a flexible nylon core with a fluorocarbon coating.

7lb Leader – Best for Clear-Water Finesse Fishing

The 7.15lb leader is the lightest and finest option in the range at 0.20mm. It is particularly suited to trout fishing in clear New Zealand rivers and lakes where a fine, low-visibility connection to a spoon, spinner, soft bait or other small lure can improve presentation.

Choose this strength when stealth and natural lure movement are more important than maximum abrasion resistance. It is less suitable around sharp rocks, heavy weed or timber where a stronger leader provides more protection.

9.48lb Leader – Light with Extra Security

At 0.23mm, the 9.48lb leader remains relatively fine but offers additional strength over the 7lb version. It is a useful option for trout in deeper pools, moderate current or areas containing some rocks, logs or weed.

For general light freshwater fishing, this strength provides a good compromise between subtle presentation and additional resistance to abrasion.

15.71lb Leader – Versatile Freshwater and Estuary Option

The 15.71lb leader steps up to 0.30mm and approximately 7.1kg breaking strength. It suits anglers who need noticeably more strength than a typical light trout leader while still wanting a relatively manageable diameter.

This makes it useful for larger freshwater fish, estuary fishing and light coastal applications where the leader may contact weed, rocks or other underwater structure.

21.34lb Leader – Stronger Around Structure

The 21.34lb leader has a 0.35mm diameter and approximately 9.6kg stated strength. It provides additional abrasion protection for heavier freshwater fishing, harbour edges, estuaries and light saltwater fishing.

Choose this strength over the lighter options when larger fish or rougher terrain make break-offs more likely, particularly when fishing near rocks, pylons, submerged timber or reef edges.

31.28lb Leader – Heaviest Option in This Range

The 31.28lb fluorocarbon coated leader is the strongest and thickest option currently available on this page. Its 0.45mm diameter and approximately 14.2kg stated breaking strength make it better suited to more demanding coastal fishing.

It can be used for species such as snapper, kahawai and trevally where additional strength is useful, particularly around rocky shorelines, kelp, wharf structure and other abrasive areas.

Compared with the 21.34lb line, the 31.28lb version sacrifices some fineness for greater strength and abrasion protection. Choose it when toughness is more important than using the smallest possible leader diameter.

Why Use Leader Line with Braid?

Braided main line provides excellent sensitivity and strength for its diameter but has relatively poor abrasion resistance around sharp structure and is highly visible compared with a clear leader. Adding fluorocarbon-coated leader line gives the terminal section of the setup additional abrasion protection and a less conspicuous appearance underwater.

The leader can be attached to braid using a suitable line-to-line knot such as an FG, Albright or Uni-to-Uni knot. The lure, hook or swivel is then attached to the opposite end of the leader.

How Strong Should My Leader Be?

Leader strength does not always need to exactly match the breaking strain of your main line. Consider the target species, water clarity and the amount of abrasive structure where you are fishing.

• 7-10lb: clear-water trout and light freshwater fishing.
• 15-16lb: larger freshwater fish, estuaries and lighter coastal use.
• 21lb: stronger fish and increased protection around structure.
• 31lb: heavier coastal use where rocks, kelp or other abrasive structure are a greater concern.

Fluorocarbon Coated vs Pure Fluorocarbon

The products on this page are fluorocarbon-coated leader lines, rather than solid 100% fluorocarbon. They use a nylon core with a fluorocarbon outer coating. This construction provides a flexible leader that is easy to tie while offering reduced underwater visibility and improved abrasion resistance.

If deciding between strengths, use the lightest leader that provides sufficient strength and abrasion resistance for the conditions. This keeps the terminal tackle less bulky while still providing appropriate protection against the fish and structure you expect to encounter.
