Wire size for zebra midge?

[a23fish]

I tied a few zebra midges at my beginner's fly tying class last week, and have the hooks, beads, and thread to try it on my own, but my local fly shop was out of the silver wire I wanted to use. What size wire should I use in a #14 hook-sized zebra midge?

small on a 14, extra small on 16 and smaller
