Nice tie on the Mickey Finn, Mike. I have always enjoyed the simplicity, the long history and the fish catching ability of that pattern. I really like to tie them on size 12 hooks for native brookies. There is just something special about catching a wild brook trout on a Mickey Finn.
I tied up a couple of these this evening. It's called the Metallic Caddis. The bead, wire body and slim profile gets it down into the water column real quick. They have produced well for me over the past few years in late winter/early spring. These are size 16 with Brassie size Chartruese Ultra Wire for the body.
