Korda Dark Matter Drop Off Inline Leader 30cm, The Dark Matter Drop Off Inline Leader provides maximum abrasion resistance with excellent camouflage and sinking properties to hide your end tackle from wary fish. The size 8 ring swivel will fit neatly inside a Korda Inline Lead, creating the perfect drop off lead system. A great way to dump the lead when the fishing situation requires it, for example in heavy weed. This simple but effective set up is attached to your mainline via your preferred knot and requires no additional splicing/loop tying. Our DM leaders have tungsten impregnated collars to ensure the leader lays flat to the lakebed, they also have a tested 30lb breaking strain.
