Rio Fly Lines

Overview of Rio's Trout lines

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.
