Beads on the fly

Anyone ever use beads with their fly rod? I was planning in getting a center pin but I got a fly rod for Christmas but still like the bead idea. I was looking at the soft bead variety.

I tie my own flies,  I use most for ice fishing but some in the spring bluegill. I have very little luck with beads,  plastic, tungsten etc anytime of the year.  What I found was that if you are getting fish on beads,  there is a more natural fly in your box that will destroy the beaded fly.  

The only time tungsten is a good option is if I'm fishing 20+ foot for suspended panfish.  the tungsten gets down quicker.  Then again, if the tungsten fly is working,  a big waxie on a heavier tungsten jig is better.  I just have very limited luck with beads.  I'd love them to work cause I have some super cool looking ones,  i just think they don't "work" naturally.  They don't flutter and look as natural.
