I recently just discovered this fine bug and have fallen in love. I learned how to tie them, and although not perfect, I think they will fish well, so I plan on using them as my lead fly a majority of the season. I know they are supposed to represent the larger stone/salmon flies, but just curious who fishes them year round. I am currently tying them in size 12, but plan on tying them bigger as well. They are super buggy and I see no reason why they shouldn't work well after the salmon flies have hatched out and left the river. So who else is like me and plans on fishing them year round?
