Theo’s Golden Balls Nymph
Those who use the various long-leader nymphing tactics will find this fly a very good one to get deep and stay deep. And although Theo ties it in 10 and 12, it is effective down to 18—adjusting the bead size to the hook size, of course.
I like to use it as the top fly in a two fly rig. The heavy weight keeps it right among the cupboards of the bottom. Behind it I will trail a small midge larval imitation or caddis larva style fly (a la the Czech nymphs). A great combo.
