TroutFilm
CDC emerger for New Zealand's ubiquitous Deleatidium ('mayfly') — the staple NZ river upwing.
Fish this when
Fish it on New Zealand rivers through a Deleatidium hatch, when trout are working steadily to the film instead of the fully risen dun.
Why it works
The low-riding CDC profile matches the natural's drawn-out struggle to shed its nymphal skin in the surface tension, the stage local trout feed on hardest.
