How to Rig It
Fish alone on a long fine leader or above a tiny emerger dropper when fish refuse high floaters.
How to Present It
Deliver slack-line casts and maintain a drag-free drift through flats and slow seams.
Why It Works
The low-riding silhouette and visible upright wing match vulnerable PMD duns without excessive hackle.
History
Comparadun-style mayflies became staples on technical western trout water because they present a clean mayfly footprint.
Pro Tip
When fish inspect but refuse standard PMDs, switch to CDC for a softer more natural profile.
