Scientific Anglers Amplitude Smooth MPX Fly Line

The Scientific Anglers Amplitude Smooth MPX is a weight-forward floating fly line built a half-size heavy to load fast-action rods easily. Its GPX-derived taper puts more mass toward the front of the head, helping turn over large dry flies, nymph rigs, and streamers while retaining enough finesse for controlled presentations. The smooth finish uses the AST Plus slickness additive to help line shoot through the guides and improve durability. A braided multifilament core suits cold to moderate freshwater conditions, and the line features an Improved Dry Tip, welded loops, and SA Line ID.
