While slightly lower in strength compared to nylon, the exceptional abrasion resistance of fluorocarbon makes it all but impervious to damage from wear, making for an incredibly durable line. The low initial stretch allows for good sensitivity, while like nylon, there is just enough stretch to absorb shock. The hardness of the material may take some getting used to.

• Sinking speed (specific gravity): 1.78 (fast sinking speed.)
• Moisture absorption: No
• Flexibility: Hard
• Stretch (amount of stretch at breaking point): Yes (slightly less stretch than nylon. Low initial stretch means better sensitivity.)
• Abrasion resistance: Hard surface is resistant to scratches and damage.
• Straight strength: Strong
• Knot strength: Approx. 70% of straight strength
• Refractive index: 1.42 (nearly invisible in water due to the refractive index being close to that of water (1.33)).
