This is the "Night Leech". Black marabou under tail, tied up shank of hook to provide body, Black bunny strip tied in at bend and tie in reinforced with copper wire, black Estaz body, bunny strip tied in at head, Black webby saddle hackle on these, black phesant rump is better, and nice finished head. Can be tied weighted or not. Swap flies are not weighted. Can be tied in a variety of colors for different situations. Fish on any type of line. I fish it unweighted in Lenore on an intermediate line. Weighted on an intermediate line in Lenice. Petite Estaz can be substituted for a slimmer profile. Still experimenting. Probasco gets credit for this pattern.
