How to Rig It

Fish it alone during PMD hatches or behind a more buoyant searching dry.

How to Present It

Allow the fly to sit low in the film and drift naturally through feeding lanes.

Why It Works

PMD cripples stay exposed longer than healthy duns, giving trout an easier meal.

History

PMD cripple patterns became go-to flies on western rivers with long midday mayfly windows.
