Dubbing Brush Nymph

For many anglers on this side of the Atlantic, Czech Nymphing is still a pretty foreign idea. While we may, or may not choose to employ this short line method of fishing heavy nymphs, there is no doubt that the effectiveness of this approach makes it worth a second look. We can, and should take advantage of growing interest in this facet of the sport, and decide where it fits into our own approach.
One of the resources i’ve found to be the most helpful is the website of Jan Siman. www.siman.cz Jan has been a member of the Czech national team, and has competed in several world championships. In 1992, Jan founded Siman Ltd.~a company that specializes in products and materials geared for angers interested in the Czech approach. Drawing on decades of experience, Jan offers and amazing selection of specialty/custom materials and tools that will no doubt get you re-thinking the way you approach your nymph tying this year. One of the more spectacular offerings is a product he calls the “Turbo Spinning Block.”

Dubbing brushes are not a new idea, but this slick tool makes them faster, and more consistently than any other method. How does it work? Jan Siman is one step ahead of you there, have a look at his “Siman Fly Fishing Channel” on youtube and click on the video that shows how simple the Turbo Spinning Block is to use. http://www.youtube.com/jansiman If you’re like me, and appreciate ANYTHING that makes buggy-looking nymphs so durable, so quick to tie…you’ll want to give the Turbo Spinning Block a try!



Now…to the pattern! The Dubbing Brush Nymph below is simply a caddis pupa-like nymph that employs two of Jan Siman’s products, as well as a dubbing brush made on the TSB. Once the dubbing brushes are made, this pattern is probably faster to tie than any other nymph. When you consider how easy it is to customize every aspect of these dubbing brushes, the options are endless.

Dubbing Brush Nymph Fly Pattern

Hook:Any curved shank/pupa hook size #8-#16
Thread:Brown 8/0
Weight:Med. lead wire
Ribbing:4X or 5X leader material
Shell Back:Jan Siman’s “Magic Shrimp Foil” pearl
Body:dubbing brush, spun up on Jan Siman’s “Turbo Spinning Block”
Legs:Jan Siman’s “Oliver Edwards Caddis Legs” in 06Brown
Dark Brown permanent marker


Wrap 3/4 of the hook shank in lead wire as shown, secure with thread on both ends. The thread should be tied to create a taper that will make the material lay down more easily~as shown. Tie on the 4X leader material, then the shrimp foil at the rear of the hook shank, facing back. Next, tie in your dubbing brush and advance the thread up towards the eye of the hook.

Wind the dubbing brush forward in tight wraps, covering about 3/4 of the hook shank. Tie off, and remove the tag end of it.


Tie in the Caddis Legs (they’re like a dubbing brush thats been made from brown deer hair) and wind them forward, stopping just behind the eye of the hook. Tie off, and remove tag end. Using sharp scissors, trim the top of the fly so that the shell back will lay flat~both the fibers sticking up from the dubbing brush, and the disheveled-looking caddis legs.


Pull the Magic Shrimp Foil forward so that it is even along the top of the fly and secure it (under tension) with several tight wraps of thread. Trim off the excess, leaving a little behind.


Make several more tight wraps of thread, forming a thread “head.” Trim the legs to a realistic length, but not all to the SAME length. Trim any fibers from the dubbing brush that take away form the overall grub-like profile of the fly.


Using the permanent marker, color the shell back above the legs, the head to match…if you like!

The finished fly!

Jan Siman Products in Canada!
I was pleased to speak with the good folks at “The First Cast” fly shop recently as I made the rounds at a couple of fishing shows in Toronto this spring. They are carrying a variety of Jan Siman products, including custom dubbing brushes, foils, and caddis legs..probably more by now. Feel free to stop by and take a look at the quality brushes their in-house expert Arron Varga is spinning up! (I could probably learn alot from Arron…the man is an artist on the Turbo Spinning Block!)
