Korda IQ2 Fluorocarbon Extra Soft Hooklink Fishing Line All Sizes. IQ2 Fluorocarbon is a softer version of our legendary IQ. Just like the original IQ, IQ2 is nigh-on invisible in water. The way that light passes through the material is quite close to the way that it moves through water, rendering your hook links very difficult for carp to detect.
