Ive added this stuff to tails of streamers with great results. Like others have stated it is great used in spent wings. One thing I did do with great luck for Great Lakes salmon (in the streams) is tie wolly buggers using nothing but glow in the dark flashabou (except for a bead head and the hackle). It worked great in the early morning. Caught a few salmon (coho) on it and had lots more strikes (some kings and coho). All in all a great material to use when you need that little something extra.
