This exceptional leader and tippet material is made
from 100% fluorocarbon (PVDF). Fluoroflex® Plus is the strongest,
thinnest fluorocarbon on the market with an incredible strength; for
example, 5 lb for 5x material. It is a slightly softer material than
Fluoroflex and ties excellent knots. The refractive index (1.42) of
Fluoroflex Plus in water (1.33) compared to nylon (1.62) makes it
almost invisible to fish.Fluoroflex Plus, with a density of 1.72
(compared to nylon of 1.15), sinks quicker and gets below the surface
tension for more effective dry fly, nymph and wet fly fishing. 7x -
0.015 inches. 30 yds (27.5 m). Also available Guide Spools of 110 yds
(100 m) in 6x - 2x.
