Addicted and Avid
There seem to be numerous variations of this fly in books and especially online. Which, makes me wonder, "What is the only true and real Thunder & Lightning Pattern and Recipe?".
I believe the fly you are referring to was an early rendition of the Black Dog.I seem to recall coming across a very old dressing for this pattern somewhere that was a very basic mostly black fly with an olive mohair head.... very basic. Anyone else come across this dressing?
