I'd tend to go nymph, but only if quite cold. Once the season is up and running, I use my brilliant CDC and Herl, which offers fish a nice gobful of black and peacock, hanging below th meniscus always loved by trout. It took loads of trout for me last season in these situations, so much so that I stopped using it! CDC isnt very durable either, no matter what people will tell you.
I also like an ant/beetle pattern made of foam, but despite reasonable tying skills, cant get the sighter post to sit upright.
So Phil at Spidersplus will be getting an order very soon as I'm sick of trying!
