Great fly to use by itself or dropped off the back of a hopper. Lots of colors work - green, red, copper, black, brown, chartreuse. I like to tie them using 2 pieces of Ultra Wire in different color and size - for example, I'll use brown wire in Brassie and copper in Small - gives a bit of a ribbed effect that I think looks cool (fish probably don't care, but they do eat them). I usually tie up 6 before I mix the epoxy for the wing case then just apply to them all at once. If you're looking for some good tutorials, check out Charlie Craven's:

Charlie also has a 2 minute (2 minutes!!!) video on tying one, too:
