The **KyleBooker 1 DZ IF19-6 RS2 Emerger Blue Wing Olive (BWO)** is a must-have in any angler’s fly box, especially when targeting selective trout in rivers and streams. In this guide, we’ll break down why this fly is so effective, how to choose the right size, and when to use it for optimal results.
## **Why the KyleBooker RS2 Emerger BWO?**
The **Blue Wing Olive (BWO)** is one of the most prolific mayfly hatches across North America and Europe, making it a staple for fly fishermen. The **KyleBooker RS2 Emerger** is designed to imitate the **nymph-to-dun transition stage**, where trout often feed aggressively.

– **Durable materials** – Built to withstand multiple strikes while maintaining shape.
– **Available in multiple sizes** – Ensuring versatility for different hatch conditions.
## **Choosing the Right Size**
The **KyleBooker RS2 Emerger BWO** comes in various sizes (typically **#16 to #22**), and selecting the right one depends on:
### **1. Hatch Conditions**
– **#16-#18** – Best for early-season or larger BWO hatches.
– **#20-#22** – Ideal for late-season or smaller, more selective trout.
### **2. Water Clarity & Flow**
– **Fast, choppy water** – A slightly larger fly (#16-#18) is easier to see.
– **Slow, clear water** – Downsize to #20-#22 for a more natural presentation.
### **3. Trout Selectivity**
If fish are refusing your fly, try **dropping a size**—trout in heavily pressured waters often key in on tiny emergers.

### **Presentation Tips**
– **Dead-drift with a slight twitch** – Mimics a struggling emerger.
