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!
