Would you believe it if I told you that jig hooks don’t change the way a nymph rides in the water? You don’t need a jig hook to invert the nymph. In fact almost all nymphs invert, especially when weighted with a bead or lead. Furthermore, nymphs built on a jig hook probably aren’t inverting the way you imagine. And how you attach the knot is much more important than the hook itself . . .
