RIO’s Leviathan line for big game fish is built on a super strong Powerflex® core (in excess of 60 lbs breaking
strength) with a tough, tropical saltwater coating. Made to tackle a behemoth on a fly rod, it’s ideal for tuna,
trevally, billfish, dorado and other bluewater species. The heavy head loads up powerful bluewater rods while the
aggressive front taper makes casting ultra large streamers and poppers relatively simple. The fly line can be cut
from the back end to 60 ft to increase the backing capacity of reels and decrease the drag through the water.
Captain Gene Quigley on the Leviathan Lines
"...Fighting Tuna and Billfish on the fly is no easy task, make one mistake and you're out of the game. Offshore fly fishing requires fly lines to be constructed of strong mono cores, and fast tapers to deliver large flies to extremely fast pelagic game fish. The heavy head on the various Leviathan fly Lines loads twelve to sixteen weight fly rods and delivers large flies quickly and accurately to breaking tuna. Additionally, the 72 pound Powerflex core allows my clients to put everything into the fight while knowing the line won't fail.
Weather your casting surface poppers to Marlin and Dorado in tropical waters, or delivering flies to 100 Pound Bluefin Tuna on the Northeast, the Leviathan lines always get the job done."
