The Amplitude Smooth series of lines are, simply put, the highest-performance smooth fly lines in the world. With up to five times less drag and eight times the durability of traditional lines, this will change the way you look at fly line performance.


Tarpon. Bonefish. Permit. All in one day. All on one fly line. That’s the idea behind the Amplitude Smooth Grand Slam, a line designed specifically to help you achieve one of angling’s most elusive accomplishments. With a short, powerful head the Grand Slam cuts through wind and turns over crabs, shrimp, and tarpon toads with ease. We’ve got the line. You just need the fish.

Features - 
  • Revolutionary AST Plus slickness additive for superior shooting ability and increased durability
  • The perfect line for bonefish, tarpon, and permit on the flats; also great for snook, redfish, and sea trout
  • Overweighted by .75 sizes to load rods quickly; use designated line weight for your rod
  • Short, powerful head turns over long leaders with heavy flies
  • Tropi-Core technology remains stiff and slick in tropical environments
  • SA AMP SMTH GR SLAM WF X F (X = line weight)
