I bet you could tie up a small herd of Zebra/Mercury midges like this:
#22 scud hook
thread body with silver wire rib
bead head - mercury (optional; dirt cheap at any craft store) or silver brass
You get good at them in a hurry, but even ugly ones catch fish and tailwater trout really like them. Here's a couple good SBSs:
