Dutch FF,
May I suggest two patterns, a Deceiver and a Clouser. I believe you can get recipes by selecting fly-tying and the archives on the left hand menu. Lefty's Deceiver and Bob Clouser's Minnow are so universal that they work almost anywhere I have fished. There are many other good flies, but these are two of the most universal I know. They are also easy to tie, which matters a great deal to me as I am one of the worst tiers you have ever run across.
