Scientific Anglers Mastery Series Billfish Line


Is it really a good idea to throw flies at fish that have either swords on their faces or thousands of razor-sharp teeth? We thought so too. That’s why we designed the Mastery Billfish line. Built on a 65-lb. core, it won’t be confused with a bonefish line anytime soon; it’s designed to throw massive flies to giant fish. Get your fly out there and hold on for the ride.


  • The ultimate choice for casting huge, wind-resistant flies to sailfish and marlin
