1 meter extra heavy Tungsten Rig Tubing 2mm.
The best solution you'll find if leaders are prohibited on the water you're fishing. I use 1 meter of Rig Tube per rod. The Rig Tube is extra heavy (8.8gr per meter). The last meter lies flat on the bottom and protects the carp during the fight. The Rig Tube is the standard 2mm size and fits perfectly into our WK Lead System.
