**Is Kylebooker Semperfli Classic Waxed Thread 8/0 105D Flouro Yellow Worth the Investment? A Fly Tying Enthusiast’s Review**
For fly fishing enthusiasts, the quality of tying materials can make or break the success of a fly pattern. One product that has gained attention in recent years is the **Kylebooker Semperfli Classic Waxed Thread 8/0 105D Flouro Yellow**. But does it live up to the hype? In this review, we’ll examine its features, performance, and overall value to determine whether it’s a worthwhile addition to your fly-tying toolkit.
### **Product Overview**
The **Kylebooker Semperfli Classic Waxed Thread** is a high-performance tying thread designed for precision and durability. The **8/0 thickness** (approximately 0.15mm) makes it ideal for delicate flies, while the **105-denier fluorocarbon coating** enhances strength without adding bulk. The **waxed finish** ensures smooth handling and reduces fraying, a common issue with cheaper threads. The **Fluoro Yellow** color provides excellent visibility during tying, which is especially useful for intricate patterns.
### **Performance Evaluation**
1. **Strength & Durability**
Unlike standard nylon threads, this fluorocarbon-coated thread resists breakage, even under tension. The waxed surface further prevents unraveling, making it reliable for securing small hooks and delicate materials.
2. **Knot Security**
The thread’s slightly textured surface improves knot-holding ability, reducing slippage—a critical factor when tying midges or dry flies.
3. **Ease of Use**
The smooth wax coating allows for consistent wraps without excessive twisting, which is particularly helpful for beginners. The bright yellow color aids in tracking wraps, ensuring neat, even layers.
4. **Versatility**
While optimized for small flies (e.g., midges, emergers), it’s also suitable for larger patterns when used in multiple layers. The fluorocarbon coating adds water resistance, making it a solid choice for wet flies.
### **Price vs. Competitors**
At **mid-range pricing**, the Kylebooker Semperfli thread sits between budget options (like UNI-Thread) and premium brands (such as Veevus). While not the cheapest, its **fluorocarbon enhancement and waxed finish** justify the cost for serious tyers who prioritize longevity and precision.
### **Potential Drawbacks**
– **Limited Color Range**: The Fluoro Yellow may not suit all patterns, though it’s excellent for visibility during tying.
– **Overkill for Beginners**: Casual tyers might find cheaper threads sufficient for practice.
### **Final Verdict**
The **Kylebooker Semperfli Classic Waxed Thread 8/0 105D Flouro Yellow** delivers exceptional strength, ease of use, and durability, making it a **high-value choice** for intermediate to advanced fly tyers. While beginners could opt for more affordable options, investing in this thread pays off in the long run with fewer breaks and cleaner finishes.
**Rating: 4.5/5**
**Recommendation**: A smart buy for anglers who demand reliability and precision in their fly-tying materials.
