Airflo Sixth Sense 2 Sweep Fly Line
Specifically designed to create a ‘U’ shape sink path, the Airflo Sweep lines cover a range of depths effectively during a single cast. Available in a range of sink rates for precision depth control, making them the ideal ‘searching’ lines.
The diving action of your flies getting pulled downwards by the belly creates an attractive movement. The steeper angle at the end of the retrieve gives an almost vertical motion when using faster sinking models, making them absolutely perfect for fishing ‘Strip & Hang’ techniques.
Sink Rates
| Sinker Type | Tip Sink Rate (inches per second) | Belly Sink Rate (inches per second) |
|---|---|---|
| Di3 | 1.5 | 3.0 |
| Di5 | 3.5 | 3.5 |
| Di7 | 5.0 | 5.0 |
FAQ

The Sweep Fly Line performs well in varying depths. I used it for strip and hang fishing in a river and noticed the flies moved naturally. The Di5 model gave a good balance between tip and belly sink rates, making it easy to control depth.

Great for searching in different layers. The U-shaped sink path helps cover more depth without needing to change lines. The Di3 was useful in shallow areas, while Di5 worked better in mid-depth zones.

I’ve tried several sweep lines, and this one stands out for its consistent performance. The belly sink action creates a realistic fly movement. Perfect for targeting fish in deeper water with a natural retrieve.
