My favorite dry-fly pattern for the Baetis hatch continues to be the Parachute Adams. It works well on my area trout, and from what I hear, on trout all over the country. I tie some with black wings, too, which show up better in situations where the sun produces a lot of glare.
Trout seem to like the bold wing silhouette, too.
Sparkle Duns, Thorax patterns, and the traditional Adams. These attractor patterns are easy to see on the water and catch fish, too. There are many times when just getting your fly small enough to suit the fish will be enough to catch a good percentage of them. Solid casting skills, using the reach cast , and dead-drifting exacting presentations will add up to catching fish. Casting skills are most important.
