# **How to Choose the Rio Mainstream Type 3 Full Sink Fly Line**
As an angler, selecting the right fly line is crucial for a successful fishing experience, especially when targeting deep-water species.

## **Understanding Full Sink Fly Lines**
Before diving into the specifics of the **Rio Mainstream Type 3**, it’s essential to understand what a **full sink fly line** is. Unlike floating or intermediate lines, full sink lines are designed to descend rapidly, allowing anglers to present flies at deeper depths effectively. The **Type 3** designation refers to its sink rate—approximately **3 inches per second (IPS)**, making it ideal for moderate to deep water conditions.
## **Key Features of the Rio Mainstream Type 3 Full Sink Fly Line**
1. **Fast-Sinking Performance**

– The **uniform density core** ensures a smooth, consistent sink without hinging or coiling.
2. **Durable & Smooth Coating**
– Rio’s **high-quality PVC coating** provides excellent durability and abrasion resistance.
– The **low-stretch core** enhances sensitivity, allowing for better strike detection.
3. **Versatile Applications**

4. **Affordable Yet High-Performance**

## **How to Choose the Right Rio Mainstream Type 3 Line**
When selecting this fly line, consider the following factors:
### **1. Fishing Environment**
– **Fast-moving rivers & deep pools:** The **Type 3 sink rate** helps get flies down quickly in strong currents.
– **Lakes & reservoirs:** Effective for reaching **weed edges, drop-offs, and submerged structures** where fish feed.
### **2. Rod Weight & Line Matching**
– The **Rio Mainstream Type 3** is available in **weights 3 through 10**, ensuring compatibility with most fly rods.
– For **trout fishing**, a **4-6 weight** is ideal.
– For **bass & pike**, opt for a **7-9 weight** for better turnover of larger flies.
### **3. Fly Selection & Retrieval Speed**
– Best paired with **heavy streamers, weighted nymphs, and large baitfish patterns**.
– A **slow, steady retrieve** works well, but experiment with **strips and pauses** to trigger strikes.
### **4. Leader & Tippet Considerations**
– Use a **short, stout leader (3-6 ft)** to maintain direct contact with the fly.
– Fluorocarbon tippets (8-12 lb) are recommended for **better sink rate and abrasion resistance**.
## **Final Thoughts**
The **Rio Mainstream Type 3 Full Sink Fly Line** is an excellent choice for anglers who need a reliable, fast-sinking line to target fish in deeper waters. Its **affordability, durability, and performance** make it a great addition to any fly fisherman’s arsenal.
