We started out using mono went to Fluorocarbon went back to try mono and back again to Fluorocarbon. I guess it depends on the water you are fishing at times our water here is simply so clear that any advantage you can give me i will take. With low light Snapper i do not think it matters that much but flicking lures around for Flathead in clear water a metre or so deep with the sun high in the sky i have gained a real confidence in the Fluorocarbon.
So we made the decision to stay with Fluorocarbon and sticking with it. generally purchasing it from OS but out of stock at the moment.

Like a lot of others we tie longer leaders and use them all day unless we get well and truly bricked. Changing leaders in the middle of a fish is something we try and avoid.
We will revisit Vanish and look at some of the Sunline products. Is there any feedback of the Sunline FC
