This extremely flexible, tungsten loaded rig tube possesses the ideal combination of flexibility and sinking ability. The Heavy Flex can be combined with Pole Position (inline) lead systems and will fully follow the contours of different bottom types. During the fight the tube protects the fish from damage and due to its characteristic elasticity the tube will not break. Because the tube has a bore (inner diameter) of 0.7mm, feeding a main line or pre-strand will be a piece of cake.
