Premier RIO Grand



RIO's Premier RIO Grand fly line is a full line size heavy for fast-action rods and a little help getting rods to load and cast efficiently.  The Premier RIO Grand is an excellent floating fly line choice not only for fast-action rods, but for anglers looking for the rod to load better on shorter casts.  The RIO Grand is an excellent all-purpose floating line and does well for fishing large dry flies, indicator nymph fishing, light to medium streamers and for casting in windy conditions.  The addition of RIO's new SlickCast simply makes the Premier RIO Grand an impressive line to cast with a noticeable upgrade to the slickness of the line while also being designed for optimum durability.

Here is what RIO has to say about their Premier RIO Grand Fly Line:

Improved for 2020!! The RIO Grand is a full line size heavier than the industry standard, and features more weight distributed towards the front of the line to easily load faster action fly rods. Built with a short head that is easy to cast, this line is also an excellent choice for novice casters who need a little more "feel" when casting. 

We have enhanced the performance of this great trout line by building it with SlickCast - RIO's proprietary coating technology. SlickCast creates the slickest, most durable fly lines on the market. Lab tests show that lines built with SlickCast have the least amount of friction ever measured in a fly line. In addition, the line features MaxFloat Tip Technology, RIO's proprietary tip coating formula that floats more than twice as high as regular line tips, without any increase in diameter.

The RIO Grand is the best choice of line for the modern, fast action fly rod.
