Scientific Anglers Amplitude Trout Fly Line


Nail the Presentation

New ideas, novel designs, and fly fishing all share one thing in common — presentation is key. One misstep and you miss hooking your audience and drawing them in. While Scientific Anglers can't help you with your business presentations, they can give you a leg up when it comes to casting with the Amplitude Trout Fly Line. This floating fly line features a compound taper that lets you achieve subtle deliveries with even the largest dry flies, small nymphs, and streamers. A weight-forward design pairs well with the AST Plus slickness additive, letting the line shoot farther and easily shedding dirt and grime you may have picked up throughout the day.
