I like to use Emu feathers for wooly worms/buggers in lieu of the regular stiff rooster hackle. I also use Emu in lieu of spun hackle on wet flies. Here is a link to a fly I use for crappie with good results. While the picture shows a gray fly I prefer olive. Emu dyes easily.

In addition Hans W's site has some neat Emu ideas. When you log onto his site hit the search feature and type in Emu. Link to Hans site: http://www.danica.com/flytier/

Hope this helps.
