Mauser, I' ll second the wolleybuggers and the bead head hare' s ear, both are great all around flies. I generally go with darker colors on the bugger- brown, olive, black, etc.

You might also consider some REALLY small(sz 18-22 or smaller) griffith' s gnat dries. If you can find a spot where the sun' s hitting the water on a reasonably warm day you might find some very small gnats hatching. They' re basically impossible to see on the water(at least for me), but they' ll occasionally draw a strike when nothing else is working.

With the distances you' re casting you certainly don' t need a knotless tapered leader, but a tapered leader will help the dries turn over a little better. You can build one yourself by nail knotting a section of fairly stiff mono to the fly line and then blood knotting progressively lighter sections of mono to that. For example, you could nail knot 3' of 15lb to the flyline, then blood knot 3' of 10lb to that, and finally blood knot 3' of 5lb on the end. Presto, tapered leader. When the section of 5lb gets too short, just replace it.
