I don't know nothing about flies, but it looks great to me.
Looks like a great multispecies bullet. Change the size up and you go from rock bass to stripers and everything inbetween.
I would want one with a black back too. A couple of my favorite lures are a rattle trap black back and a spook with a black back.
Nice work. Soon as we get this house sold, a new one bought and moved and settled in I get to set up a desk to tie flys. Sugar Callous promised. I am looking forward to that.
