    Not enough history yet

    • Familiarity: I've used it once or twice and have initial impressions

    Just added this to my 4 wt sage rod and a hatch reel. I like it so far seems to cast really well and presents well in a dry situation

    Great line!

    • Familiarity: I've used it several times

    Pairs very well with my TFO BVK fast action. I have no problem sending a nymph sailing 20 yards with this guy and I can softly float a dry down with ease. It is all very intuitive with this line, great purchase!

    Good Fly line makes a huge difference

    • Familiarity: I've used it several times

    I love this line, I use it on my Vapen black 6wt rod and it is a stunning line. Very good line to compliment fast action rods. I've mainly used this line on the Provo and Weber rivers and it was perfect by my standards. I am excited to take it to a larger river.

    Go-To Fly Line

    • Familiarity: I've put it through the wringer

    I rigged this line for my fast action Vapen rod. RIO makes quality lines and this is no exception. I primarily fish small/medium size rivers and this is perfect for those conditions. Highly recommend if you fish in similar conditions with a fast action rod.

    Dreamy casting

    • Familiarity: I've put it through the wringer

    I recently upgraded to the Rio Grand Fly Line and I am glad I did. This line complements the fast action of my Sage One 9ft 5w rod. I typically fish small to medium sized rivers for all species of trout and this line performs exceptionally well on fast action rods for those conditions.

    Awesome line

    • Familiarity: I've put it through the wringer

    I replaced my SA GPX with this line and I like it quite a bit better. It shoots faster and I can get more line out there with fewer false casts. It's easy to pick up 50+ ft of line and throw it back out there with no false casts. Also, leaders seem to dig into the loop connection less than the GPX (removing a heavily loaded leader was damn near impossible). I also like the dualtone marking system a lot. My rod is a med-fast action. I almost got the Gold, but my local fly shop talked me into this one.

    Go-to trout line

    • Familiarity: I've put it through the wringer

    I use this line most often since I have a fast-action Sage VXP and fish mid-size rivers for trout. The line floats great and is easy to cast. This is a great line for the price.

    Great on a fast rod!

    • Familiarity: I've put it through the wringer

    If you're fishing a medium sized river with a fast rod, this line is great. Definitely helps to load the rod at shorter distances. I use this for primarily double nymph rigs and streamer fishing on the Weber and Provo and have no complaints. Not the most delicate presentation out there, but if you're throwing a line 30ft or less on a super fast rod, you still get the energy from the rod. If you're routinely casting longer distances with a fast rod on a lake, I'd go with the Rio Gold as your more standard line.
