I really messed up the body by making it too long and not getting it in a ball central to the hook shank for the thorax. Nevertheless, it floated. I will say I did not find the instructions crystal clear as to how to tie the fly. Forgive me, it was my first attempt. No excuse, I had his to look at and still botched the job.
Old habits are hard to break.
This is not an easy fly to learn. Once learned, however, it is very simple. Next time, we go underwater and take a look.
