Chasing after bonefish, permit, and tarpon requires a specialized tool. In order to get the grand slam, you need to use the Scientific Anglers Amplitude Smooth Grand Slam. Designed with a short front taper to turn over heavy flies with long leaders, the Grand Slam is the perfect fly line for chasing after the pinnacle of saltwater fly fishing. Constructed with the AST Plus slickness additive, Grand Slam lines are 50% slicker than previous SA lines, and will last, on average, eight times longer than others on the market.
Remember: REAL NERDS GET ALL THE FISH.
there was no mention of the new smooth line in this vid by the way.
