Black Pennell was my all time most killing fly on Hebridean lochs. Pretty much had one on every team of three, below top fly.I don't think anyone is claiming that such 'evergreens' as Black Pennell, Blae & Black, Greenwells, etc are outdated, are they?
What we are looking for are flies that no one has used for many years, surely?
Step forward anyone who has been using the following recently:
Hardy's gold butcher
Grouse and green
Woodcock and mixed
Teal and yellow
... to name but a few...
