Seaguar Soft Plus 50m
A great advantage to the Riverge Soft Plus is that it will give your flies more natural movement in the water as they will move along with the water's current, with less resistance from the line. However due to its softness care should be taken to avoid wind knots.
The Riverge Grand Max Soft Plus fluorocarbon has proven to be 100% reliable and has a high resistance to abrasion and fatigue. It could even be used as a reel line and is definitely soft enough for this purpose.
