The Airflo 7000 Series Fast Glass 105 ft / 35 yd Fast Sinking Intermediate line in WF-10-I (Weight Forward, 10-weight, Intermediate sink rate) is designed for anglers who need a fast-sinking fly line to reach deeper water quickly while maintaining casting efficiency. Here’s a breakdown of its key features:

Key Specifications:
– Model: Airflo 7000 Series Fast Glass
– Length: 105 feet (35 yards)
– Sink Rate: Fast-Sinking Intermediate (typically sinks at ~1.75–2.5 inches per second, though exact rates vary by brand)
– Line Weight: WF-10-I (Weight Forward, 10-weight, Intermediate)
– Core: Polyfuse (Airflo’s durable, non-PVC coating bonded to a strong core)
– Technology: Ridged Technology (improves shooting ability and reduces friction)

Best Uses:
– Deep-Water Fishing: Ideal for targeting fish holding in deeper zones (striped bass, pike, muskies, lake trout, etc.).
– Saltwater & Big Flies: The 10-weight rating makes it suitable for large flies and windy conditions.
– Fast Sinking: Gets flies down quickly without the extreme density of a full-sink line.

Pros:
✔ Durable Coating: Airflo’s Polyfuse material resists cracks and memory.
✔ Smooth Casting: Weight-forward design aids in distance with heavy flies.
✔ Low Stretch Core: Enhances sensitivity for better strike detection.

Cons:
❌ Not for Floating/Suspending: Purely a sinking line—not ideal for topwater or shallow presentations.
❌ Intermediate Sink Rate: May not be fast enough for extreme depths compared to Type 3–6 lines.

Comparables:
– RIO InTouch DeepFull Sink (for deeper, faster sink rates)
– Scientific Anglers SONAR Sink 25/30 (similar fast-sinking performance)

Final Verdict:

Airflo 7000 Series Fast Glass 105 ft / 35 yd Fast Sinking Intermediate - WF-10-I

This line is excellent for anglers needing a fast-sinking intermediate option in a 10-weight, especially for saltwater or large freshwater predators. If you need a slower sink or floating alternative, consider Airflo’s Ridge Striper (floating) or Super-DRI Elite (versatile sink rates).
