The Hends 554 combines several families of rigs for subsurface fishing. You can tie classic nymphs, nymphs with bead or Heavy Body weight, as well as caddis pupae, gammarids, and Czech nymphs.
For a weighted fly, start by choosing the size of the imitation, then attach the bead or weight to the hook before building the body. The 554 model features a barb and a Black Nickel finish. The selection includes sizes #10, #12, and #16, all in packs of 25.
