Slow Intermediate Fly Line - Sixth Sense 2 - Airflo

Slow Intermediate Line (Slow Inter) - Sixth Sense 2 - AIRFLO

The Airflo Sixth Sense 2 is the benchmark for technical lake and stillwater fly fishing. This Slow Intermediate (Slow Inter) version is purpose-built for fishing just under the surface film, where fish feed on buzzers and small nymphs. Its sink rate of 0.5 ips (about 1.25 cm/s) keeps you in the strike zone as long as possible without dropping too quickly.

What makes this fly line unique is Airflo's renowned Power Core. With near-zero stretch (only 6 %), it delivers outstanding sensitivity: you feel the faintest micro-takes at range, and your hook sets are instantaneous, even on fish that are just "nipping".

Its Delta Taper profile (long front taper) ensures clean energy transfer for long, accurate casts, while keeping the presentation subtle so as not to spook fish.

Detailed features

Key strengths

- Absolute Sensitivity: Power Core turns your rod into a true sensor; you can feel what's happening at the other end of the line.

- Long Casting: Its 14 m head is perfectly stable, helping you gain those crucial extra metres.

- Reduced memory: Thanks to polyurethane, the fly line stays straight and coil-free, even in cold weather.

- Surgical hook set: The lack of stretch means hook-set energy is transmitted instantly to the hook.

La Fine Mouche's take: The Sixth Sense is a stillwater legend, and this version 2 improves the glide even further. The "Slow Inter" is the must-have line for all spring fishing when fish patrol just under the surface.
