RIO's Fluoroflex Strong is the top of the range, highest quality fluorocarbon that RIO sells. The material is 100% fluorocarbon, and not only has exceptionally high tensile strength, but is also very easy to tie knots in, with high knot strength and a smooth finish that ensures knots seat easily and tightly.
The high break strength to diameter ratio makes this a fantastic fluorocarbon for the trout fly fisher in the lighter sizes, while the heavier sizes are more abrasion resistant and tougher, making the material ideal for the Spey, streamer, and Saltwater angler.
Each spool has 30 yards of top quality material spooled on, though for those who use a lot of fluoro, our guide spools each have 100 yards spooled on.
Fluoroflex Strong is also available in a “3-Pack”, which includes three, 30-yard spools of tippet packaged in a reusable, clear plastic cup. The 3-Packs are available in both a 4X, 5X, 6X option, & a 3X, 4X, 5X option.
