# **How to Choose the Best 3 Trout Flies: 4mm Fluorescent Green Tungsten UV Yellow Pulling Leech**
As an angler, selecting the right fly can make the difference between a successful day on the water and going home empty-handed. Among the many options available, the **4mm Fluorescent Green Tungsten UV Yellow Pulling Leech** stands out as a highly effective pattern for trout fishing. In this guide, we’ll break down why this fly is a must-have in your tackle box and how to choose the best variations for different fishing conditions.
## **Why the 4mm Fluorescent Green Tungsten UV Yellow Pulling Leech?**
This fly is designed to mimic a leech, a natural food source for trout in both still and moving waters. Its key features include:
– **Tungsten Bead (4mm):** Provides rapid sinking, allowing the fly to reach deeper holding zones quickly—ideal for fast currents or deep pools.
– **Fluorescent Green & UV Yellow:** Highly visible in low-light conditions and murky water, attracting aggressive strikes.
– **UV Enhancement:** Increases visibility underwater, making it irresistible to trout even in stained water.
– **Pulling Leech Design:** The slim profile and pulsating movement imitate a fleeing leech, triggering predatory instincts.
## **How to Choose the Right Variation**
When selecting this fly, consider the following factors:
### **1. Water Conditions**
– **Clear Water:** Opt for a more subdued color blend with subtle UV accents to avoid spooking wary trout.
– **Stained or Murky Water:** The fluorescent green and UV yellow shine best, enhancing visibility.
– **Fast Currents:** The tungsten bead ensures the fly stays in the strike zone despite strong flows.
### **2. Trout Behavior & Season**
– **Spring & Fall:** Leeches are active, making this pattern highly effective. Use brighter colors in early spring and darker tones in late fall.
– **Summer:** Fish deeper with the tungsten bead as trout seek cooler water.
– **Winter:** Slow retrieves with slight twitches work best—trout are less active but still target easy meals.
### **3. Hook Size & Weight**
– **Smaller Hooks (Size 12-14):** Ideal for selective trout in pressured waters.
– **Larger Hooks (Size 8-10):** Better for aggressive fish or when targeting bigger trout.
– **Tungsten Bead Size:** A 4mm bead is perfect for medium-depth fishing; go heavier (5mm+) for deep pools.
## **Best Fishing Techniques**
To maximize success with this fly, try these retrieves:
– **Slow Strip & Pause:** Mimics an injured leech, enticing hesitant trout.
– **Short, Quick Strips:** Triggers reaction strikes from aggressive fish.
– **Dead Drift in Current:** Let the tungsten bead bounce naturally along the bottom.
