## **When to Use the DZ D18-3 HI-VIZ Griffith’s Gnat Tan**
This fly excels in several scenarios:
### **1. Midge Hatches**
– Midges are a staple food source for trout year-round. The Griffith’s Gnat is an excellent imitation, especially in sizes **#18–#22**.
– The **HI-VIZ post** helps track the fly when midges are hatching in dense swarms.
### **2. Low-Light & Overcast Conditions**
– On cloudy days or early mornings, the high-visibility post ensures you don’t lose sight of your fly.
– Works well in **slow-moving pools and tailwaters** where subtle takes are common.
### **3. Selective Trout Feeding on Small Insects**
– When trout are keyed in on tiny insects but ignoring larger patterns, downsizing to a **#20 or #22** can trigger strikes.

## **How to Choose the Right Size**
The **DZ D18-3 HI-VIZ Griffith’s Gnat Tan** comes in multiple sizes, and selecting the best one depends on:
### **1. Match the Hatch**
– Observe the natural insects on the water. If midges are small (like **#20–#22**), go with a smaller fly.
– In early spring or late fall, slightly larger sizes (**#16–#18**) may work better.
### **2. Water Conditions**
– **Fast Water:** A slightly larger fly (**#16–#18**) is easier to see and stays buoyant.
– **Slow, Clear Water:** Smaller sizes (**#20–#22**) appear more natural to wary trout.
### **3. Fish Behavior**
– If trout are rising but refusing your fly, try downsizing.
– If they’re aggressively feeding, a **#18** might be the perfect balance between visibility and realism.

– **Use a Fine Tippet (6X–7X)** for a natural drift, especially with smaller sizes.

– **Dead-Drift Presentation** is key—avoid drag to mimic a natural insect.
