An Overview of the RIO Gold Series: A Legacy of Innovation
RIO has built a reputation for pushing the boundaries of fly line technology. From advanced coatings that increase slickness and durability to innovative core materials that enhance sensitivity, their commitment to performance is evident. The Gold series embodies this ethos, offering a range of tapers and technologies born on legendary trout waters like the Henry’s Fork River in Idaho. Each line in the series is thoughtfully designed with specific payload distributions and intentional designs to empower anglers across diverse fishing scenarios. All series Weight Forward fly line.
SlickCast
SlickCast improves casting distance and durability on Rio Gold fly lines primarily because it creates the slickest, most durable coating ever measured on a fly line. The key reasons are:
- Reduced Friction: SlickCast produces a very low-friction surface on the line, meaning it slides through the rod guides with significantly less resistance. This allows the line to shoot faster and farther under the same casting effort, improving casting distance and efficiency.
- Long-lasting Slickness: The coating continuously releases slickening agents that keep the surface slick over time. This ensures that the line stays slick and easy to cast even after extended use.
- Increased Durability: SlickCast coatings are much tougher and more resistant to cracking and abrasion than conventional fly line coatings. Lab tests show lines with SlickCast last 33% longer before cracking and endure 140% more abrasion cycles than the nearest competitors, resulting in a significantly longer lifespan.
- Better Shooting and Mending: Less line friction means anglers can feed line more easily for extended drag-free drifts and achieve smoother, more precise mends with less effort.
In summary, SlickCast’s proprietary coating technology directly improves the line’s ability to shoot with less effort and resist wear and tear, making Rio Gold lines perform better for longer periods.
ConnectCore Plus
ConnectCore Plus in Rio Gold fly lines significantly improves hook-setting and sensitivity by providing an ultra-low stretch core. This core stretches about 30% less than standard fly line cores, which delivers several key benefits:
- Enhanced Sensitivity: The reduced stretch allows anglers to feel even the slightest takes or movements on the fly line more directly. Subtle bites become more noticeable, helping to detect strikes that might otherwise go missed.
- Faster and More Positive Hook Sets: With less stretch in the line, the energy from a hook-setting motion is transmitted more efficiently and immediately to the fly. This results in quicker, firmer hook sets and reduces wasted energy during the process.
- More Direct Connection: The low-stretch core allows for a straighter line on the water and a more direct connection between the angler, the fly, and the fish. This improves overall control during casting, mending, and fighting fish.
- Hand Stretching for Less Memory: ConnectCore Plus allows easy hand stretching to remove memory coils, maintaining straighter line and better contact.
Overall, ConnectCore Plus makes the angler more responsive and effective when setting hooks and increases the tactile feedback from fishing, which can improve catch rates and fishing success.
This explanation is based on technical overviews and expert tests of Rio’s ConnectCore Plus technology.

Comparison: RIO Gold Elite vs. Premier
When choosing between RIO’s popular Gold series, anglers are often met with two excellent options: the top-tier Elite and the high-performing Premier. While both lines share the same versatile taper design, the primary difference comes down to a combination of core technologies, on-line features, and ultimately, price.
Before diving into the differences, it’s important to note what these lines share. Both the Elite and Premier series feature RIO’s game-changing SlickCast coating. Lab tests have shown SlickCast to be the slickest, most durable fly line coating ever developed. This technology dramatically reduces friction as the line flies through the guides, resulting in longer casts with less effort. It also enhances durability, ensuring the line remains slick and resists cracking over extended use.
Elite Series: The Pinnacle of Performance
The Elite lines are RIO’s top-tier offering, designed for anglers who demand the absolute best in performance and tactile feedback. The key features that set the Elite series apart include:
- ConnectCore Plus: The Elite lines are built on a ConnectCore Plus low-stretch core. This core dramatically increases sensitivity, allowing you to feel the faintest takes for faster, more positive hook sets. Simon Gawesworth from RIO explains that this low-stretch core eliminates the “bungee effect” common in standard lines, providing better control when fighting a fish—especially when needing to turn it away from weeds—and more direct energy transfer during casting.
- SureFire™ Triple Color System: This three-color marking system provides a clear visual reference for casting. The first color indicates the tip, the middle color identifies the optimal loading point or “sweet spot” of the line, and the third color is the running line. This system helps anglers gauge distance and execute the perfect cast by knowing exactly when to let the line fly.
- Easy ID™: The Elite series includes a printed ID system directly on the line, showing the line’s taper and weight. This feature eliminates guesswork and the need for sticky labels on your reel, making it easy to identify which line is which.
Premier Series: High Performance, Accessible Price
The Premier lines offer exceptional performance at a more accessible price point, making them a fantastic choice for a wide range of anglers. While they include the same high-performance SlickCast coating as the Elite series, they differ in the following ways:
- Standard Core: The Premier lines are built on a standard, regular-stretch core. While this core doesn’t offer the heightened sensitivity of ConnectCore Plus, it does have one notable advantage: the slight give in the line can help protect light tippets and delicate hook holds on small flies.
- DualTone Color System: The Premier series features a two-color system that marks the transition between the head and the running line. This provides a helpful reference point for knowing when to pick up the line for a recast, though it is less detailed than the Elite’s SureFire system.
Both the Elite and Premier series feature high-floating tips and welded loops on both ends for easy rigging. Ultimately, the choice between them hinges on an angler’s priorities: the Elite series is for those who need maximum sensitivity and the most advanced casting features, while the Premier series offers outstanding slickness and durability for budget-conscious anglers who still demand a reliable and long-lasting fly line.
Best RIO Gold Lines for Specific Techniques
Best for Small Dry Flies
For presenting tiny dries on long, delicate leaders, the Avid Trout–Gold and Premier Gold are superb choices. Their standard-weight, long-head taper allows for gentle laydowns and precise casts, preventing you from spooking wary trout.
Best for Larger Dry Flies & General Trout Fishing
When your day involves a mix of larger attractor dries, hoppers, and dry-dropper rigs, the Elite Gold or Premier Gold XP excel. The classic Elite Gold provides the control needed for distance presentations, while the Gold XP’s extra power helps turn over slightly larger flies with ease.
Best for Streamers & Heavy Rigs
If you’re throwing streamers, double-nymph rigs under a large indicator, or heavy foam flies, the Elite Gold Max and Premier Gold Max are your best allies. Their full-size heavy, compact heads are designed specifically to handle unwieldy setups, making casting feel powerful and effortless rather than a chore.
Best for Extreme Conditions
Don’t let the weather dictate your fishing. For icy winter days, the Premier Glacial Gold remains supple and memory-free. For sweltering summer heat that would turn other lines into noodles, the Premier Dog Days Gold stays firm and slick.
Line Size Sorting Guide
Matching your fly line weight to your fly rod is crucial for optimal casting performance and presentation. An improperly matched line can make even the most expensive rod—like the premium models in our ultimate guide to the Sage 5-weight fly rod—feel clunky and inefficient. Here is a simple guide to the available line weights for each model in the RIO Gold fly lines series, so you can easily find the right match for your rod.

Expert’s Take: An On-the-Water Review
As an avid angler, I’ve had the pleasure of fishing numerous lines, but I often return to the Gold series for its reliability. I currently have the RIO Gold Avid WF6F with my LOOP Evotec rod, and it has been an absolute workhorse. Its balanced feel makes it a joy to cast all day long. I’ve used it to present small size #18 dries with the necessary delicacy, yet it has no trouble turning over a larger hopper-dropper rig when the situation calls for it. The line mends beautifully, allowing for long, natural drifts, and its versatility across different conditions makes it a staple in my gear bag.
Conclusion: The Gold Standard for a Reason
The RIO Gold fly lines Series has earned its place as one of the most versatile and highly recommended fly line families on the market. With options tailored for every technique, condition, and budget, it truly empowers anglers to perform at their best. By understanding the nuances between the Elite, Premier, and Avid tiers—and matching the taper (Classic, XP, or Max) to your primary fishing style—you can select a line that feels like a natural extension of your rod.
