Dylan Turner –
Used this line in coastal areas with strong winds and hot sun. The coating stayed firm and the line performed well with large flies. Easy to cast and handled well in windy conditions.
James Arnold –
Good all-around saltwater fly line. Holds up well in tropical heat and works well with heavy flies. A bit stiff at first, but breaks in after a few uses.
