I have not been able to locate a source for the tapered dry fly hackles that make the Bivisibles so distinctive. In the early 1960's we did not have roosters that were carefully bred for optimal hackle properties. Then our hackle feathers would have shorter barbs at the tip, with the barbs became progressively longer toward the base. Thus we needed to use two hackles on a Catskill dry in order to avoid differences in barb length.
A Bivisible takes advantage of the tapered hackle. Does anyone know where I can get decent necks with the tapered feathers? Thanks.
