Hook: 25 mm shank

A spey-style swing fly from Greg Senyo for Great Lakes steelhead, built on a short 25 mm shank with a wire loop at the back to carry a trailing hook. Layers of white, speckled silver and electric blue flash sit under paired kingfisher blue and white schlappen, a guinea collar and jungle cock cheeks, with bead chain eyes turned to the underside. Fish it on the swing, and change the colors to suit the water conditions. Tied here on a 25 mm shank.

How to Tie the Senyo's Artificial Intelligence

  1. 1

    Step 1

    Clamp the 25 mm shank in the vise and start the GSP thread with a tight base along the shank.

  2. 2

    Step 2

    Double a length of intruder wire and lash both ends along the shank so a loop extends past the back of the shank for the trailing hook. Trim the ends.

  3. 3

    Step 3

    Tie the bead chain eyes in at the front of the shank with crossing wraps, then rotate them to the underside of the shank.

  4. 4

    Step 4

    Tie in the XL pearl cactus hackle and wind it in touching turns to build a bright base for the wing. Tie off and trim.

  5. 5

    Step 5

    Tie in a small bunch of Lady Amherst center tail fibers on top so they trail back over the shank.

  6. 6

    Step 6

    Tie in a bunch of white Flashabou on top and trim it to length.

  7. 7

    Step 7

    Add a layer of speckled silver Flashabou over the white.

  8. 8

    Step 8

    Tie in a bunch of electric blue Flashabou, then finish the flash with a little more white Flashabou over it.

  9. 9

    Step 9

    Pair a kingfisher blue and a white schlappen feather and tie them in together by the tips. Wind them as one in front of the flash, stroking the fibers back with each turn, then tie off and trim.

  10. 10

    Step 10

    Tie in a natural guinea feather by the tip and wind a sparse collar in front of the schlappen, sweeping the fibers back.

  11. 11

    Step 11

    Tie a jungle cock cheek on each side of the head.

  12. 12

    Step 12

    Build a small, neat head, whip finish and cut the thread.

  13. 13

    Step 13

    Coat the head with Loon UV Clear Fly Finish Thin and cure it with a UV light.
