Two CDC plumes tied flat over a thread body — Marjan Fratnik's minimalist genius. Sits in the film rather than on it, exactly where small olives get trapped.
Fish this when
Spring and autumn when tiny olives (size 18–20) are hatching. Fish it in the hatch window on clear, calm water with fine tippet.
Why it works
Minimal outline of a small mayfly. Easy to track on the water. Selective trout and grayling take it confidently when nothing else works.
