# **How to Choose the Scientific Anglers Sonar Grand Slam Clear Tip Fly Line – WF11F/I – 136365**
As an avid angler and fishing gear enthusiast, I’ve had the pleasure of testing numerous fly lines, but few stand out like the **Scientific Anglers Sonar Grand Slam Clear Tip Fly Line (WF11F/I – 136365)**. Designed for serious saltwater and big-game fly fishing, this line delivers exceptional performance in challenging conditions. If you’re considering adding it to your setup, here’s a detailed guide to help you make an informed choice.
## **Understanding the Key Features**
### **1. Weight Forward (WF) 11F/I Design**
The **WF11F/I** designation means this is a **weight-forward, floating/intermediate** line. The **weight-forward taper** helps load heavy rods quickly, making it ideal for casting large flies or battling powerful fish. The **clear intermediate tip** (about 10 feet) ensures a stealthy presentation, crucial for wary saltwater species like tarpon, permit, and bonefish.
### **2. Clear Tip Technology**
The **Sonar Grand Slam** features a **clear intermediate tip**, which reduces visibility in clear water. Unlike brightly colored floating lines, the transparent section prevents spooking fish, especially in shallow flats or crystal-clear coastal waters.
### **3. Superior Slickness & Durability**
Scientific Anglers coats this line with their **AST (Advanced Shooting Technology) Plus slickness treatment**, ensuring smooth, friction-free shooting through guides. The **high-density core** provides excellent turnover power, while the **aggressive front taper** aids in casting bulky flies with precision.
### **4. Saltwater-Ready Construction**
Built for **saltwater anglers**, this line resists **UV damage, abrasion, and cracking**. The **stiffer core** prevents coiling in tropical heat, and the **low-stretch design** enhances sensitivity for solid hook sets.
## **Who Should Use This Line?**
– **Saltwater fly anglers** targeting **tarpon, permit, snook, and striped bass**.
– **Big-game fly fishermen** needing a line that can handle **heavy flies and strong winds**.
– **Anglers fishing clear, shallow flats** where stealth is critical.
## **How to Choose the Right Setup**
– **Rod Pairing**: Best matched with a **10-12 wt fly rod** for optimal performance.
– **Reel Selection**: Use a **large-arbor saltwater reel** with a strong drag system.
– **Leader Choice**: A **9-12 ft fluorocarbon leader (16-20 lb)** complements the clear tip for maximum stealth.
## **Final Verdict**
The **Scientific Anglers Sonar Grand Slam Clear Tip Fly Line (WF11F/I – 136365)** is a **top-tier choice** for serious saltwater fly fishermen. Its **clear intermediate tip, superior casting performance, and durability** make it a must-have for targeting wary gamefish.
