Something I threw together over the weekend and have NOT actually fished with yet...Its probably been done by others?
Here's the idea behind it...the large beadchain eyes placed close to the hook eye, with large hackle tied behind it, so the fly will sit somewhat "tail-up" on the bottom of the lake/pond/stream. The rubber has excellent action in the water, and the fish should hold onto it fairly long. The ball of dubbing at the hook bend keeps the rubber from sliding down the shank.

The 2nd picture shows the "yellow" rubber lit up under UV light, while the purple stays subtle.






And below is a trio of Myakka Minnows:
