Developed in collaboration with Sunline Japan to achieve optimum leader performance, Aftco Saiko Pro Fluorocarbon Leader seeks to give both inshore and offshore anglers an unfair advantage over the competition. Saiko Pro Fluorocarbon features a supple yet hard finish that provides unprecedented abrasion resistance and knot strength. Testing has shown Saiko Pro to be up to 20% stronger after abrasion than other fluorocarbon leader materials, allowing you to have confidence in your leader’s strength after dozens of uses. The 12lb - 80lb test comes on Aftco’s SecureSpool that makes for easy leader storage without the mess from uncoiled and disorganized leader spools, while the 100lb? 300lb test coils come with a weather resistant leader bag that protects the leader from the elements and maintains line longevity.
