# **How to Choose Hareline Brass Dumbbell Eyes Fly Tying Materials – Black Nickel 3.2mm**

As an avid fly tyer, selecting the right materials is crucial for creating effective and durable flies. One of the most essential components for weighted patterns is **Hareline Brass Dumbbell Eyes**—particularly the **Black Nickel 3.2mm** version. These eyes provide the perfect balance of weight, durability, and aesthetics, making them a top choice for streamers, nymphs, and saltwater patterns.

In this guide, we’ll break down why these dumbbell eyes are a must-have in your fly-tying kit and how to choose the right size and finish for your needs.

## **Why Choose Hareline Brass Dumbbell Eyes?**

### **1. Superior Weight & Sinking Performance**
The **3.2mm Black Nickel Brass Dumbbell Eyes** are made from high-quality brass, ensuring excellent density for fast-sinking flies. Unlike plastic or bead-chain eyes, brass provides the necessary weight to get your fly down quickly in strong currents or deep pools—ideal for streamer fishing or deep nymphing.

### **2. Black Nickel Finish for Durability & Stealth**
The **Black Nickel plating** offers two key advantages:
– **Corrosion Resistance** – Unlike bare brass, the black nickel coating prevents tarnishing, making these eyes perfect for both freshwater and saltwater applications.
– **Low Visibility** – The dark finish reduces flash, making your flies appear more natural to wary fish like trout, bass, and even saltwater species.

### **3. Perfect Size for Versatility**
The **3.2mm diameter** strikes a balance between being large enough for good weight distribution while remaining subtle enough for smaller patterns. This size works well for:
– **Streamers** (Woolly Buggers, Clouser Minnows)
– **Nymphs** (Stoneflies, Dragonfly Nymphs)
– **Saltwater Flies** (Crazy Charlies, Shrimp Patterns)

## **How to Select the Right Dumbbell Eyes for Your Flies**

### **1. Consider the Fly Size & Weight Needs**
– **Smaller Flies (Size 10-14 Hooks):** If you need a lighter option, consider **2.5mm or 3.0mm** dumbbell eyes.
– **Medium to Large Flies (Size 6-2/0 Hooks):** The **3.2mm** size is ideal for most weighted streamers and nymphs.
– **Extra-Heavy Flies (Saltwater/Sinking Patterns):** For maximum weight, opt for **4.0mm or larger** brass eyes.

### **2. Choose the Right Finish**
– **Black Nickel (Best All-Around):** Great for low-visibility and durability.
– **Gold or Silver (For Flashy Patterns):** Useful for attracting fish in murky water or aggressive species like pike and bass.

### **3. Secure Attachment for Longevity**
To ensure the dumbbell eyes stay firmly in place:
– **Use strong thread wraps** (e.g., UTC 140 Denier or Gelspun).
– **Apply a drop of super glue** before wrapping for extra security.
– **Cover with thread or epoxy** to prevent loosening over time.

## **Final Thoughts**

The **Hareline Brass Dumbbell Eyes in Black Nickel 3.2mm** are a premium choice for fly tyers who demand quality, durability, and performance. Whether you’re tying streamers for bass, nymphs for trout, or saltwater patterns for redfish, these eyes provide the perfect balance of weight and stealth.
