RIO Gold vs. Perception vs. InTouch — Which RIO Line is Right for You?

The RIO Gold is the industry's best-selling trout line — a versatile WF taper with a moderate head that handles dry flies, nymphs, and streamers with equal competence. The Perception adds a longer head and improved mending characteristics for technical dry-fly and indicator work. The InTouch lines reduce stretch dramatically for Euro-style and tight-line nymphing where feel is everything.

Frequently Asked Questions

Q: What RIO fly line should I start with?
The RIO Gold in your rod's stated line weight is the default recommendation for most trout anglers. It casts well, mends reliably, and handles the full range of standard trout techniques without compromise. If you develop a preference for specific techniques, RIO makes specialized lines that optimize for each.

Q: How do I clean my RIO fly line?
RIO recommends cleaning lines with their Agent X line dressing or a mild soap and warm water solution after every few uses. Dirt and grit embedded in the coating accelerate wear and reduce slickness significantly. A clean line casts farther, floats higher, and lasts longer.
