RIO's Leviathan Fly Line is for big game fish and 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, its 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.
The line is available in two types:

- 400 grain (60 lb core)
