I am sure you would agree with me when I say there are some days when the Trout just aren't playing out.  On those days, try this little beauty.  This Olive and black tadpole is absolutely deadly wherever you fish it and is one of the best flies for Trout I have ever used. Tying this fly on is almost cheating!!  See YouTube video for how to tie it and how to fish it!!  Tight lines folks!!  https://youtu.be/u69IlYEUuQk
