For the last week I have been working on my first ever worm box, and one of the synthetic materials I have been using in place of Standard Ultra Chenille to tie my San Juan Worms is a Hareline product called Pearl Core Braid. As it's name suggest it has a core that comes in a variety fish catching colors, and is surrounded by a clear pearl braided flash. Trust me when I tell you that the photos aren't doing the material justice, and that this worm pattern will shred lips!
In fact, I would be stunned if they didn't catch fish in the Pueblo tailwater during the coldest days of winter. These would also do great on the South Platte tailwaters after a bump in flows or during runoff. The "sex band" on the worm is a thread base covered in Clear Cure Goo and then coated with Sally Hansen's. Other than that it's tied just like a typical San Juan. I will say that there is a trick to melting and forming the ends of the Pearl Core Braid, and that it has to be done or the fly falls apart. If I get any interest in seeing how this is done I will gladly do a video to show off the technique.
