Everybody needs a squirmy wormy fly pattern in their fly box, and this one is devastatingly effective on trout streams. We designed ours with a CDC collar for extra movement and appeal, and tied them on a barbless jig hook with a tungsten bead to create the ultimate squirmy worm pattern.
The following are the bead sizes per hook:
Size 12 - 3.8 mm
Size 14 - 3.3 mm
