# **How to Choose Shrimp Bodies Fly Tying Material: Tungsten Scud & Tungsten Alloy Fly Fishing**
As an avid fly angler, selecting the right materials for tying effective shrimp patterns can make a significant difference in your success on the water. Shrimp imitations, particularly scud patterns, are essential for targeting trout, panfish, and even saltwater species. One of the most crucial components of these flies is the **shrimp body material**, and tungsten-based options like **Tungsten Scud and Tungsten Alloy** have become game-changers in modern fly tying.
In this guide, we’ll explore how to choose the best shrimp bodies for fly tying, focusing on tungsten-based materials, their advantages, and how to use them effectively.
## **Why Tungsten for Shrimp Bodies?**
Tungsten is one of the densest metals available, making it an excellent choice for fly tying when weight and durability are priorities. Compared to traditional materials like lead or brass, tungsten offers:
– **Superior sink rate** – Gets flies down quickly in fast currents or deep pools.
– **Compact size** – More weight in a smaller profile for a natural appearance.
– **Durability** – Resists corrosion and maintains shape over time.
– **Environmentally friendly** – Many tungsten alloys are non-toxic, making them a safer choice for aquatic ecosystems.
## **Tungsten Scud vs. Tungsten Alloy: Which One to Choose?**
### **1. Tungsten Scud Bodies**
Tungsten scud bodies are pre-formed, bead-like components designed specifically for scud and shrimp patterns. They come in various sizes (1.5mm to 4.5mm) and colors (pearl, olive, tan, etc.) to match different aquatic invertebrates.
**Best for:**
– Quick and easy fly tying (simply slide onto the hook).
– Small to medium-sized shrimp patterns.
– Stillwater or slow-moving currents where a subtle sink rate is needed.
### **2. Tungsten Alloy Wire or Sheets**
Tungsten alloy materials come in wire or thin sheet form, allowing for more customization in fly tying. These are wrapped around the hook shank to create a weighted underbody before adding dubbing or other materials.
**Best for:**
– Larger shrimp or crayfish patterns requiring extra weight.
– Saltwater flies where a streamlined profile is crucial.
– Anglers who prefer a fully customizable weight distribution.
## **Key Factors When Choosing Shrimp Body Materials**
1. **Hook Size & Fly Profile**
– Smaller hooks (size 14-18) pair well with tiny tungsten beads (1.5-2.5mm).
– Larger patterns (size 8-12) benefit from tungsten wire or 3.5-4.5mm beads.
2. **Water Conditions**
– Fast currents or deep pools: Use denser tungsten alloy wraps.
– Slow-moving or shallow water: Opt for smaller tungsten scud beads.
3. **Color & Realism**
– Natural tones (olive, tan, gray) work best in clear water.
– Brighter colors (pink, orange) can trigger strikes in murky conditions.
4. **Tying Technique**
– For bead-style bodies, secure them with thread or UV resin.
– For tungsten wire, wrap evenly and cover with dubbing for a seamless look.
## **Top Fly Patterns Using Tungsten Shrimp Bodies**
– **Tungsten Scud (Sowbug/Amphipod Imitation)** – A must-have for trout in tailwaters.
– **NearNuff Shrimp** – A saltwater favorite with a tungsten underbody for quick sinking.
– **Czech Nymph (Tungsten Bead Version)** – Works well as a freshwater shrimp mimic.
## **Final Thoughts**
Choosing the right shrimp body material can elevate your fly patterns from average to irresistible. **Tungsten scud beads** offer convenience and consistency, while **tungsten alloy wraps** provide flexibility for custom weighting. By considering water conditions, hook size, and tying techniques, you can create highly effective shrimp patterns that fool even the most selective fish.
