The go-to fly line for all freshwater species.

Scientific Anglers Amplitude Smooth fly lines deliver some of the highest performance found in any smooth fly line on the market.  These Scientific Anglers fly fishing lines are made with AST Plus slickness additive for incredible shootability and increased durability.  AST Plus in the Amplitude Smooth fly lines provides up to 5 times less drag and 8 times the durability of traditional fly lines.

The Scientific Anglers Infinity taper is designed to be the ultimate "do it all" freshwater fly line from panfish and trout to steelhead and pike.  These SA fly lines are made a half size heavy to help load modern fast action fly rods while still being very comfortable with a range of fly rod actions.  The length of the taper in these general purpose fly lines are long enough for easy mending and stability at a distance.  Amplitude Smooth Infinity fly lines provide enough power to turn over larger streamers while still being delicate enough to present dry flies.  If you are looking to buy a very versatile, all purpose freshwater fly line the Amplitude Smooth Infinity line is a winner!
