The Scientific Anglers Amplitude Smooth Infinity PLUS Fly Line (WF4F – 142878) is a high-performance fly line designed for versatility and smooth casting. Here’s a detailed breakdown of its key features:
Key Features:
1. Weight Forward (WF4F)
– Designed for 4-weight rods, ideal for freshwater trout, small stream, and delicate presentations.
– Weight-forward taper enhances casting efficiency, making it easier to load rods at short to medium distances.
2. Amplitude Series Technology
– Slicker, Durable Coating – Features Scientific Anglers’ proprietary AST (Amplitude Smooth Technology) for reduced friction and longer casts.
– Low-Memory Core – Minimizes coiling for smoother performance in cold or warm conditions.
3. Infinity Taper Design
– Optimized for all-around performance, balancing delicacy and power.
– Smooth turnover for accurate presentations, whether dry flies, nymphs, or small streamers.
4. Enhanced Durability
– Microsphere-Infused Coating – Resists cracks and abrasions for extended lifespan.
– Welded Loops – For easy leader attachment without knots.
5. Color & Identification
– Moss Green (standard for SA freshwater lines) with clear tip for visibility.
Best Use Cases:
– Trout fishing in rivers, streams, and lakes.
– Delicate dry fly presentations with minimal splash.
– Nymphing & small streamer work where a smooth turnover is needed.
Pros:
✅ Ultra-smooth casting with reduced friction.
✅ Durable coating resists wear and cracking.
✅ Versatile taper for multiple techniques.
✅ Low memory for better cold-weather performance.
Cons:
❌ Higher price point compared to budget lines.
❌ May be overkill for very small streams (some anglers prefer a DT line for short casts).
Competitor Comparison:
– vs. Rio Gold – Smoother and more durable, but Rio Gold has a slightly more aggressive taper for punchy casts.
– vs. Orvis Pro Trout – Similar performance, but the Infinity PLUS has better cold-weather handling.
Final Verdict:
A premium fly line for anglers who want a smooth, durable, and versatile 4-weight line for trout fishing. Ideal for those willing to invest in high-end performance.
