# **How to Choose Jim Vincent’s Rio MainStream Trout Full Sink Fly Line**
When it comes to fly fishing for trout, having the right fly line can make all the difference between a successful day on the water and a frustrating one. Among the top choices for anglers targeting trout in deeper waters is **Jim Vincent’s Rio MainStream Trout Full Sink Fly Line**. This specialized sinking line is designed to help you reach the strike zone quickly and maintain control over your presentation. But how do you choose the right one for your needs? In this guide, we’ll break down the key factors to consider when selecting this premium fly line.
## **1. Understanding the Full Sink Design**
Unlike floating or intermediate lines, a **full sink fly line** is built to descend rapidly, allowing you to effectively fish deep pools, lakes, and fast-moving currents where trout often hold. The **Rio MainStream Trout Full Sink** line is engineered with a **uniform sinking rate**, ensuring a consistent depth throughout your retrieve.
– **Sink Rate:** This line typically sinks at **4.5 to 6 inches per second (IPS)**, making it ideal for depths of **6 to 15 feet**.
– **Taper & Control:** The weight-forward taper helps with casting accuracy, while the sinking design keeps your fly in the strike zone longer.
## **2. Matching the Line to Your Rod & Fishing Conditions**
Choosing the right **line weight** is crucial for optimal performance. The **Rio MainStream Trout Full Sink** is available in **weights 3-6**, making it compatible with most trout rods.
– **For Small Streams & Light Rods (3-4 Weight):** Best for delicate presentations in shallow-to-medium depths.
– **For Larger Rivers & Stillwaters (5-6 Weight):** Provides better turnover for weighted flies and deeper sinking performance.
Additionally, consider:
– **Water Type:** Fast rivers require a faster sink rate, while lakes may need a more controlled descent.
– **Fly Size & Weight:** Heavier nymphs and streamers pair well with a 5 or 6-weight line for better turnover.
## **3. Durability & Performance Features**
Rio is known for high-quality fly lines, and the **MainStream Trout Full Sink** is no exception. Key features include:
– **Durable Coating:** Resists cracks and abrasions, extending the line’s lifespan.
– **Low-Memory Core:** Reduces coiling for smoother casting and fewer tangles.
– **Saltwater & Freshwater Versatility:** Though designed for trout, it performs well in various environments.
## **4. When to Use a Full Sink Line vs. Other Options**
While floating lines are great for dry flies, and intermediate lines work well for shallow presentations, the **full sink line excels in:**
– **Deep nymphing** – Getting your flies down quickly in fast water.
– **Streamer fishing** – Keeping bulky flies at the right depth for aggressive trout.
– **Lake fishing** – Reaching trout holding near the bottom in stillwaters.
## **5. Final Tips for Choosing the Right Model**
– **Test Cast If Possible:** Some fly shops allow demo casts to feel the line’s performance.
– **Check the Color:** High-visibility colors (like olive or dark green) help track the line in murky water.
– **Pair with a Quality Leader:** A **9-12 ft fluorocarbon leader** reduces visibility and improves sink rate.
## **Conclusion**
The **Rio MainStream Trout Full Sink Fly Line** is a top-tier choice for anglers who need precision and depth control in their trout fishing. By considering the **sink rate, rod compatibility, water conditions, and fly type**, you can select the perfect line for your setup. Whether you’re targeting big browns in deep pools or casting streamers in a lake, this line will help you get your fly where the fish are.
