The Tungsten Crystal Midge is an extension of the popular Zebra Midge. I fish this pattern in sizes 16 down to 22 and use a little Solarez Bonedry to coat the body of the fly for durability. The Tungsten Crystal Midge is a great choice for pressured water either river or still water. Use a bead head and thread that is sized to the hook you are using. One the smallest flies I use 70d Ultrathread because it lays flat. I prefer the UNI-French oval tinsel, but a silver wire works great as well.
