On the water
Understand it. Then fish it.
The river, depth, insects, and fish behavior still decide the final presentation. These are reviewed starting points—not a claim about what is happening today.
How to fish it
- Keep direct contact without dragging the fly faster than the current.
- Choose bead mass for the specific lane.
- Use short controlled drifts through seams and pockets.
Mistakes to avoid
- Calling every resin-bodied jig nymph the same exact Perdigon.
- Ignoring bead mass and hook orientation.
- Using more weight than the water or regulations allow.
Variant control
Small changes matter.
Three reviewed technical illustrations provide a profile, material map, and presentation view. They are identification aids, not photorealistic substitutes for tied examples.
