The Scientific Anglers Amplitude Smooth Infinity Taper Fly Line (WF-4-F) is a high-performance fly line designed for smooth casting and precise presentations. Here’s what you should know if you’re considering a used version:
Key Features:
– Taper Design: “Infinity Taper” (a hybrid between a standard weight-forward and a longer belly taper) offers versatility for both short and medium-distance casts.
– Technology:
– Amplitude Series: Features AST (Advanced Shooting Technology) coating for reduced friction and longer casts.
– Smooth Texture: Low-stretch core for better sensitivity and control.
– Durable Coating: Resistant to cracks and abrasions, even with extended use.
– Weight & Size: WF-4-F (Weight Forward, Floating, 4-weight).
– Color: Typically a muted gray or olive for low visibility.
Buying Used – Things to Check:
1. Condition:
– Look for cracks, nicks, or peeling coating (common in old/dry lines).
– Check for memory (coiling) – excessive curling reduces performance.
2. Usage:
– Ask how often it was used (saltwater use accelerates wear).
– Check if it was stored properly (UV exposure degrades fly lines).
3. Performance:
– A used line may have reduced slickness, affecting shootability.
– Test floatability if possible (waterlogged lines sink).
Pros of Buying Used:
– Cost Savings: Retail price is ~$100+; used could be 30-60% cheaper.
– Eco-Friendly: Reusing gear reduces waste.
Cons:
– Uncertain Lifespan: Fly lines degrade over time (~1-5 years, depending on care).
– Potential Hidden Damage: Micro-cracks or dirt buildup may not be visible.
Alternatives if Pass:
– New Budget Option: [Scientific Anglers Frequency](https://www.scientificanglers.com/frequency-trout/) (~$50).
– Premium Upgrade: [RIO Gold](https://www.rioproducts.com/products/fly-lines/gold) (if you prefer a more aggressive taper).
Final Verdict:
If the used line is in good condition (minimal cracks, smooth texture, floats well), it’s a solid deal for practice or backup. If heavily used, investing in a new line may be better for performance.
