As the name suggests this Heli system is designed to be used on a Leader material. We would recommend using diameters over 0.50mm so Leadcore would be perfect.
However, this system can be used on smaller diameters like mainline, if you use a Tungsten sinker either side of the line gripper
The no trace bead system allows you to fish safely with there being no problem if you get cut off.
Each pack contains 10 off each part of the system
Also available spare C beads 25 per pack
