This YGK Olltolos "Lure Special" fluorocarbon is branded as a carbon that can be used for both leaders and mainline! Personally the jury is out on it being okay for mainline, I am yet to find a fluoro that can do this, but give it a go if you are brave.
But, as a leader material I instantly saw the benefits of this zero stretch, super tough fluoro. Sometimes you need a rigid leader, surface lures spring to mind when you dont want your lure turning and finding a limp leader.
So this top spec Japanese Fluorocarbon is stiff, very low stretch and rigid....I had to get some in!
