We stock fishing line leader for the recreational and commercial use. Leader selection will be depend on species targeted, type of fishing and location.

Considerations such as visibility, chafe resistance, flexibility, tying or crimping, sacrifical breakoff, etc will ultimately influence your selection. We have a wide variety of Leader material available for purchase and we have many sizes and line breaking strains to choose from.

4 key points to consider a monos quality/suitability:

  • Breaking Strain – consistent over cross sectional diameter
  • Resistance to Chafe –  some chafe does not result in total failure
  • Diameter –  needs to be considered hook eye size along with reel capacity
  • Pliability – Do the knots pull up and stay bound
