How about using the yarnie under a float. Should I just run it in the place of a jig and run a few split shot on the leader to keep it down?
I have made the glo bug flies and fished the as jig droppers in the past but found that even with lead core wrapped around the hook that the glo bug is tied to it is still too buoyant.

How could I fish them under a float successfully, never tried but I figure might as well give it a go.
