I love this line. I find it stiff enough to turn over large flies but flexible enough to cast very well. The line has been proven by me to work well on large Redfish, Trout, Tarpon, Jack Cravalle, Bluefish, etc.

Casting
It has a shorter head for quick casts to cruising tarpon and also minimizes false casting with large flies. It has enough stiffness to turn over large flies, spoons and Bass flies as well.

Casting In Wind
The advanced taper improves line performance in the wind without compromising delivery.

Design and Fishability
It has an deal head and taper length for the optimal casting balance between distance, accuracy, and speed. It also has a Larger tip diameter and short front taper provide extra power for delivering large flies. The aggressive compound taper head provides easy turnover under the most demanding saltwater conditions.

Sink Rate
The line has a very slow sink rate of 2.0-2.5 ips. The line on sinks a few feet below the surface before the floating head stops the sink. This gets the line below the surface chop but keeps the line in the strike zone well. It also helps when using a sinking fly.

Quality
The line is about a year old has been fished hard. The line doesn't show and significant wear yet.

I like Scientific Anglers products and this line is another example of them creating a product that meets a specific need but has features that allow it to be used in a variety of circumstances. It fishes great in saltwater but also does well for bass and huge Carp in freshwater.
