How does the "Badger Bivisible" differ from other fly patterns, such as the "Lady's Fish Finder" or the "Bivisible Moose"? Is it about the shape, or the materials used in the pattern? What does it represent to the fish, when cast on the water?

I have found that all of the above patterns work, some of the time, for unknown reasons. In smaller hook sizes, (#18 and smaller) they are great during the Trico Hatches in August.

I do not have any answers to why this style of dry fly works, I just know that if the situation is right, that they do! ~Parnelli
