1) Grizzly Cluster
In faster water—and especially in bubbly seams—buoyancy is critical. This pattern, tied with grizzly hackle on a light hook, rides higher than some other clusters and helps you spot takes that you might otherwise miss with a low-riding single-midge pattern. That's important because trout rarely charge midges. They subtly suck them down. When you see this buoyant fly disappear, set the hook.
