# **How to Choose CDC F Fly, Olive, Mixed 14/16/18 – Best Dry Trout Flies**
When it comes to dry fly fishing, selecting the right pattern can make the difference between a successful day on the water and going home empty-handed. Among the most effective and versatile dry flies available today is the **CDC F Fly in Olive, Mixed sizes 14/16/18**. Designed to imitate small mayflies and other aquatic insects, this fly is a must-have in any angler’s box. In this guide, we’ll break down why the CDC F Fly is so effective, how to choose the right size, and when to use it for the best results.
## **Why the CDC F Fly?**
The **CDC (Cul de Canard) F Fly** stands out due to its natural buoyancy and lifelike movement. CDC feathers come from the preen gland of ducks, making them incredibly water-resistant while still allowing subtle movement that mimics real insects. The **Olive coloration** is particularly effective as it matches a wide range of mayflies, midges, and caddisflies—common prey for trout in many rivers and streams.
### **Key Features:**
– **Superior Floatation:** CDC fibers repel water, keeping the fly riding high on the surface.
– **Realistic Profile:** The slim body and delicate wings imitate emerging insects perfectly.
– **Versatile Sizes:** Available in **14, 16, and 18**, allowing adaptation to different hatches.
## **Choosing the Right Size (14/16/18)**
Selecting the correct size is crucial for matching the hatch. Here’s a quick guide:
– **Size 14:** Best for early-season mayfly hatches (e.g., Blue-Winged Olives) or when fish are keying in on larger insects.
– **Size 16:** A great all-around size, imitating mid-sized mayflies and caddis. Ideal for most trout streams.
– **Size 18:** Perfect for selective trout feeding on tiny midges or late-season mayflies. Requires a finer tippet (6X or 7X).
If you’re unsure, **carry all three sizes** to adapt to changing conditions.
## **When and Where to Fish the CDC F Fly**
– **Early Morning/Late Evening:** Trout are often more active during low-light periods, feeding on emerging insects.
– **Slow-Moving Pools & Riffles:** The CDC F Fly excels in slower currents where trout have more time to inspect their prey.
– **Selective Trout Situations:** When fish are refusing other patterns, the natural movement of CDC often triggers strikes.
## **Presentation Tips**
– **Dead-Drift Technique:** Keep drag-free drifts to imitate a natural insect.
– **Light Tippet:** Use 5X-7X fluorocarbon for a stealthy approach.
– **Floatant Application:** While CDC is naturally buoyant, a light silicone-based floatant can enhance performance.
