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
