This is the new Seaguar Soft Plus fluorocarbon. This fluorocarbon is much softer and is 10% stronger than the original Grand Max. This fluorocarbon has nearly the same refractive index as water making it almost invisible when placed in water and it has an exceptionally strong breaking strain compared to the low diameters. A great advantage to the Seaguar 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 Seaguar 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.
