# **How to Choose UNI Nylon EX Strong Fly Tying Thread: 70 Denier (200yds) & 210 Denier (100yds)**
When it comes to fly tying, selecting the right thread is crucial for durability, precision, and overall fly performance. **UNI Nylon EX Strong Fly Tying Thread** is a top-tier choice among anglers and fly tiers for its strength, versatility, and smooth handling. Available in two key denier sizes—**70D (200 yards)** and **210D (100 yards)**—this thread caters to different tying needs.
In this guide, we’ll break down the differences between these two thread weights, their best applications, and how to choose the right one for your fly patterns.
## **Understanding Denier: What Does It Mean?**
Denier (D) measures the thickness and strength of a thread. A higher denier means a thicker, stronger thread, while a lower denier indicates a finer, more delicate thread.
– **70 Denier (200 yards)** – A lightweight yet strong thread, ideal for small to medium flies where precision and minimal bulk are key.
– **210 Denier (100 yards)** – A heavier-duty thread, perfect for larger flies, saltwater patterns, or when extra durability is needed.
## **Key Features of UNI Nylon EX Strong Fly Tying Thread**
Before diving into specific use cases, let’s look at what makes this thread stand out:
✔ **Exceptional Strength** – Made from high-quality nylon, it resists breakage even under tension.
✔ **Smooth & Tangle-Free** – Waxes coating ensures smooth wraps without fraying.
✔ **Wide Color Selection** – Available in multiple shades to match natural insect hues.
✔ **Consistent Diameter** – Uniform thickness for clean, professional wraps.
## **When to Use 70 Denier (200 Yards)?**
The **70D** version is a favorite for delicate patterns where bulk can affect the fly’s movement and sink rate.
✅ **Best for:**
– Small dry flies (e.g., **mayflies, midges**)
– Nymphs and emergers
– Trout and panfish flies
– Detailed tying requiring fine thread control
✅ **Why Choose It?**

– Long spool (200 yards) ensures plenty of material for multiple flies.
## **When to Use 210 Denier (100 Yards)?**
The **210D** thread is built for toughness, making it ideal for flies that face aggressive strikes or harsh conditions.
✅ **Best for:**
– Saltwater flies (e.g., **bonefish, tarpon patterns**)
– Large streamers and bass flies
– Heavy-duty nymphs and woolly buggers
– Flies requiring extra durability
✅ **Why Choose It?**
– Thicker thread resists abrasion from toothy fish.
– Provides a solid base for bulky materials like deer hair or synthetic fibers.

## **Choosing the Right Thread for Your Needs**
Still unsure which to pick? Consider these factors:
🔹 **Hook Size** – **70D** for #18 and smaller, **210D** for #6 and larger.
🔹 **Fish Species** – Delicate trout? **70D**. Tough saltwater predators? **210D**.
🔹 **Fly Type** – Dry flies and nymphs favor **70D**, while streamers and saltwater flies need **210D**.
## **Final Thoughts**
Both **UNI Nylon EX Strong Fly Tying Thread** options offer reliability and performance, but the right choice depends on your specific fly-tying needs.
– **For finesse and small patterns**, the **70 Denier (200 yards)** is unbeatable.
