## **Understanding the Flamethrower Double Salmon Fly**
Before deciding on the size, it’s essential to understand why the **Flamethrower pattern** is so effective. This fly features:
– **Bright, flashy materials** – The combination of fluorescent colors and reflective tinsel mimics baitfish, triggering aggressive strikes.
– **Double hook design** – Enhances hook-up rates, especially when salmon swipe at the fly.
– **Durable construction** – Built to withstand powerful strikes and turbulent water.
The **Ultimate MP Tosh version** refines this pattern with premium materials, ensuring maximum durability and lifelike movement.

## **Choosing Between Size 8 and Size 10**
### **1. Water Conditions & Flow Speed**
– **Size 8 (Larger)** – Best for **high, murky water** or fast currents where visibility is low. The bigger profile helps salmon locate the fly more easily.
– **Size 10 (Smaller)** – Ideal for **clearer, slower-moving water** where a more subtle presentation is necessary.
### **2. Salmon Behavior & Aggressiveness**
– If salmon are **highly aggressive** (common in early runs), **Size 8** will draw more attention.
– If fish are **spooky or lethargic** (late-season fishing), **Size 10** may be the better choice.
### **3. Fishing Technique**
– **Swinging flies** – A **Size 8** holds better in strong currents and creates a more pronounced wake.
– **Dead-drifting or nymphing** – A **Size 10** sinks faster and appears more natural in slower pools.

## **Final Recommendation**
For most anglers, having **both sizes (8 and 10)** in your fly box is the best strategy. Start with **Size 8 in high water** or when fish are aggressive, then switch to **Size 10** if they’re being selective.
The **3 V Fly Ultimate MP Tosh Flamethrower Double Salmon Flies** are a must-have for serious salmon anglers. Whether you’re fishing in Scotland, Norway, or Canada, these flies will help you hook more fish.
