It depends on what you are tying. on longer flies such as a wooly bugger or
leech it adds an undulating motion - the up down motion on the retrieve as well
as adding an attractant depending upon the bead color. But this can also be
done with lead wire and crystal flash. It is a good and fast solution to many
fly enhancements (flash, motion, sinking ability esp with tungsten)

On the other hand I sometime felt that the bead heads on some flies were so
common on a stream that it was a tip off to the trout that it was an artificial
and not to be eaten.

just some thoughts ....
