Very nice Gold Bonber fly there mate.
Many moons ago, I once tied my own Gold Bomber fly but with a two hook set up and tried it up the NT and it worked a treat on Barra, Salmon and GT's etc.
Just don't ask me for a photo, because a mate of mine decided to borrow it and haven't seen it since...
I might try to tie a few more for our Awoonga trip this Oct, because I want to try for one of those big mummas on a fly rod. Good luck to me I know!
