I’d like to fish the Czech Nymphing technique for brown trout a bit more but I’m at a loss to know what patterns to try.
There’s so many different patterns out there that I’d like someone to recommend a pattern that they've had some success with to try! The thinking being that if I have confidence in the fly I’ll concentrate more on the technique! Thanks.

The patterns that imitate
Ryacophila
hydropsyche
shrimp
peeping caddis
all work but anything buggy will do.If you have a few minutes on your next trip,take a kick sample by holding a very fine mesh net downstream and shuffling over some coarse gravelled area.Imitate the commonest "bugs" you find
