I have been trying to post a picture of the upside down muddlers (without dumbell eyes, they are neutral density) but my camera isn't cooperating. Anyway, it is a standard marabou muddler, but tied so that it looks right with the hook up and all the bouyant material (marabou, estatz body, dear hair) on the inside of the hook bend. Page 33 of Farrow and Allens "Flies for Bass and Panfish" has a fly that is basically the same, just with some different wing material (and mine isn't as pretty).
