Dry Fly

Hook: 12-20

The Sulphur Comparadun, demonstrated in Tim Flagler's detailed Tightline Productions tutorial, is a flush-floating dry fly that sits in the surface film with a subtle silhouette. The upright deer hair wing and slim dubbed body perfectly mimic natural Sulphur and Hendrickson mayfly duns. This pattern excels on slow, clear water where picky trout demand a natural presentation.

How to Tie the Sulphur Comparadun

  1. 1

    Step 1

    Place the dry fly hook in the vise and start the yellow thread, wrapping a smooth base.

  2. 2

    Step 2

    Select a small bunch of short/fine bleached deer hair. Clean, stack, and measure it to one hook-shank length.

    Use 'short/fine' deer hair specifically — it flares and stands upright more easily than longer hair.

  3. 3

    Step 3

    Tie in the deer hair wing at the one-third point, positioning it upright. Use several tight compression wraps to flare the wing into a 180-degree fan shape.

  4. 4

    Step 4

    Post the wing upright with thread wraps in front, building a small thread dam to hold it vertical.

  5. 5

    Step 5

    Select 2-3 medium dun microfibbets and tie them in at the bend as split tails, using a small dubbing ball to splay them.

  6. 6

    Step 6

    Create a thin dubbing noodle with pale yellow Superfine dubbing and wrap a slim, tapered abdomen from the tail to just behind the wing.

    Keep the dubbing very sparse — a slim body is key to the Comparadun's effectiveness.

  7. 7

    Step 7

    Dub a slightly fuller thorax area around and behind the wing with the same dubbing.

  8. 8

    Step 8

    Build a small, neat thread head in front of the wing, whip finish, and apply a tiny drop of head cement.
