About this item

  • Features the 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


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.

I bought a new line to go bonefishing. I bought a 8# for an 8# rod I have. The line didn’t balance well at all and overloaded the rod. I switched back to an older #8 Rio Bonefish line on the same rod, and it cast like a dream.

I had used it before and was well satisfied with the way it floated on the water.
