FlyWorld now offers the ultimate in leader technology. Furled leaders provide perfectly controlled energy transfer between fly line and fly without imposing memory of the leader. They allow precise and delicate presentations with long, drag-free drifts. Without any treatment they are almost neutrally buoyant. With floatant applied, theyll lay gently on the surface.Leaders made with monofilament nylon or fluorocarbon retain memory. They are relatively stiff, so they coil when not stretched and lay straighter than required when they are stretched. Furled leaders never coil or spring straight, so micro drag is avoided.Leaders are suitable for line weights between 3 and 7 and are 167cm long (55).
