Why it works
- A recessed or cupped front face displaces water during a strip, adding sound and surface disturbance to the fly's visible silhouette.
- Head diameter, face depth, legs, tail volume, and pause length change how loudly the fly works, so large bass and small panfish poppers should not share one assumed cadence.
- The three named photographs make scale and construction differences visible without relabeling a slider, diver, or floating terrestrial as a popper.
