## **Why Choose Tungsten Eyes for Fly Tying?**
Tungsten has become the go-to material for fly tying weights due to its superior density compared to traditional brass or lead. Here’s why **Hareline Tungsten Eyes** stand out:
– **Higher Density**: Tungsten is nearly twice as dense as lead, allowing for a more compact weight profile while maintaining sink rate.
– **Durability**: Unlike softer metals, tungsten resists deformation, ensuring your flies stay balanced even after multiple casts.
– **Realistic Pupil Design**: The painted pupil adds a lifelike element, making your flies more enticing to predatory fish like bass, pike, and trout.

## **Key Factors When Choosing Hareline Tungsten Eyes**
### **1. Size Selection**
Hareline offers these dumbbell eyes in various sizes (small, medium, large, and extra-large). The right size depends on:
– **Target Species**: Larger eyes (3.5mm+) work well for bass and pike flies, while smaller sizes (2.0mm-3.0mm) are ideal for trout and panfish patterns.
– **Water Depth & Current**: Heavier eyes help flies sink faster in deep or fast-moving water.
### **2. Color & Pupil Effect**
The **black pupil on a metallic base** mimics natural prey eyes, increasing strike rates. Some key considerations:
– **Gold & Silver Options**: Gold works well in murky water, while silver is great for clear conditions.
– **UV Coatings (if available)**: Some versions may have UV-reactive finishes for added visibility in low light.
### **3. Attachment Method**
These eyes come in **barbed or smooth shank** versions.
– **Barbed Eyes**: Provide a secure grip when tying, reducing slippage.
– **Smooth Shank**: Easier to adjust during tying but may require extra thread wraps or glue.

## **Best Fly Patterns for Hareline Tungsten Eyes**
These dumbbell eyes excel in:
– **Jig Nymphs** (e.g., Perdigons, Frenchie Nymphs) – Improves sink rate and keeps the hook point up.

– **Bass & Pike Flies** – Enhances the jigging motion and realism.

## **Tying Tips for Maximum Effectiveness**
1. **Secure Placement**: Wrap the thread tightly around the shank before applying glue (e.g., UV resin or super glue) for a permanent hold.
2. **Balance the Fly**: Position the eyes slightly forward of the hook bend for a jigging effect.
3. **Match the Hook**: Use a **jig hook** (e.g., Firehole 631, Ahrex SA220) for optimal performance.
