One of the more successful experiments from 2012, tempting a good few fish as far afield as Skye, Orkney, Stocks, Bewl and Rutland. With nothing particular in mind food-item wise, but vaguely suggestive of fry and corixa, I'd consider it a 'suggestive attractor'. My preference is on the middle dropper, surrounded by quieter flies. Dress it with hen, and keep it on the skinny side.
