Sulphur Comparadun
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
Step 1
Place the dry fly hook in the vise and start the yellow thread, wrapping a smooth base.
- 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
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
Step 4
Post the wing upright with thread wraps in front, building a small thread dam to hold it vertical.
- 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
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
Step 7
Dub a slightly fuller thorax area around and behind the wing with the same dubbing.
- 8
Step 8
Build a small, neat thread head in front of the wing, whip finish, and apply a tiny drop of head cement.
