Rio GT (Giant Trevally) Mono – 30 yds
The ultimate Giant Trevally tippet with larger mono diameters and higher break strengths to prevent being cut off on coral and sharp structure, while supple enough to seat larger saltwater knots properly.
Most giant trevally guides will tell you that the best way to land these incredibly powerful fish is to keep them from running far enough to cut you off on structure.
Strong fluorocarbon might come to mind, but it sinks much faster than nylon at larger diameters and affects fly presentation.
That’s why the standard leader configuration for GT fishing has become level monofilament with break strength in the 100-130lb range.
RIO’s GT Mono is perfect in this application, striking the ideal balance between strength and knot security.

Jessica Brown –
Used this mono for a recent giant trevally fight and it held up perfectly. No cuts on coral, and the knot stayed secure even during a long run. Much better than fluorocarbon for this application.
Una Jackson –
Fishing in rocky reefs with strong currents, this mono didn’t break or snag. The strength and flexibility are exactly what I needed for big fish.
Felicity Scott –
Good performance in practice. A bit stiffer than expected, but it works well with my knots and doesn’t snap during heavy pulls.
Sebastian Turner –
Highly recommended for GT fishing. It’s strong, doesn’t sink too fast, and stays in place during aggressive runs. No issues with knot seating.
