# **How to Choose Trout Flies: CDC Shuttlecocks & F Flies x 10 Sizes 10, 12, 14 & 16**
When it comes to fly fishing for trout, 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, **CDC Shuttlecocks** and **F Flies** stand out as highly effective patterns. In this guide, we鈥檒l break down why these flies work, how to choose the right size (10, 12, 14, or 16), and when to use them for optimal results.
## **Why CDC Shuttlecocks & F Flies?**
### **1. CDC Shuttlecocks: The Ultimate Dry Fly**
CDC (Cul de Canard) feathers are prized in fly tying for their natural buoyancy and lifelike movement. The **CDC Shuttlecock** is designed to imitate emerging insects, particularly midges and mayflies, sitting low in the water with a realistic silhouette.
**Key Features:**
– **Superior Floatation:** CDC fibers trap air, keeping the fly afloat even in choppy water.
– **Natural Drift:** The soft fibers create subtle movement, mimicking struggling insects.
– **Versatility:** Works well in slow-moving streams and faster currents.
### **2. F Flies: The All-Rounder Nymph**
The **F Fly** is a modern take on classic nymph patterns, featuring a slim profile and flashy elements to attract trout. It imitates a wide range of aquatic insects, making it a must-have in any fly box.
**Key Features:**
– **Slim Profile:** Matches the natural shape of mayfly and midge nymphs.
– **Flash Appeal:** Incorporates subtle flash to trigger aggressive strikes.
– **Great Sinking Action:** Dives quickly and stays in the strike zone longer.
## **Choosing the Right Size: 10, 12, 14, or 16?**
The size of your fly should match the insects trout are feeding on. Here鈥檚 a quick breakdown:
– **Size 10:** Best for larger mayfly or caddis imitations, ideal in early season when bigger insects are active.
– **Size 12:** A versatile mid-range size, great for general nymphing and dry fly presentations.
– **Size 14:** Perfect for imitating standard mayflies and midges, a go-to for selective trout.
– **Size 16:** Excellent for finicky trout in clear water or when small midges dominate.
## **When to Use CDC Shuttlecocks vs. F Flies**
– **CDC Shuttlecocks:** Use when trout are rising to surface insects. Best in **hatch periods** or when fish are keying in on emergers.
– **F Flies:** Ideal for **subsurface fishing**, especially in deeper runs or when trout are feeding on nymphs.
## **Pro Tips for Success**
1. **Match the Hatch:** Observe what insects are present and choose your fly size accordingly.
2. **Adjust Depth:** For F Flies, vary your leader length and weight to reach different water columns.
3. **Use Light Tippet:** A 5X or 6X tippet helps with a natural drift, especially with smaller sizes (14-16).
## **Final Thoughts**
A well-stocked fly box should include **CDC Shuttlecocks and F Flies in sizes 10, 12, 14, and 16** to cover a variety of fishing conditions. Whether you’re targeting rising trout with a CDC dry fly or nymphing deep with an F Fly, these patterns from **KyleBooker** will help you land more fish.
