This is fun to tie but there are a few things to keep in mind when tying. You want to make sure that the abdomen is long enough. The Dai Riki #060 is a 1XL shank, ensuring that you will have enough room for a long abdomen. You also want to make sure that you keep the abdomen nice and slim. You can use 8/0 thread if you want and keep your thread wraps to a minimum. Attach the thread, wrap back and secure your tail fibers with 2 wraps. Then attach the Micro Tubing with two tight wraps, advance the thread forward, with tight wraps, securing the Micro Tubing and PT underneath. This will also ensure a slim abdomen.

I tie a few different variations of this pattern. I’ll tie them in black, red, brown and purple. I use thread for the abdomen with MFC Premium Tying Thread and use ice dubbing in the same color as the abdomen. This is a very versatile and effective pattern. Tie up a bunch and go fish them!
