FROGS!!! There is nothing more exciting than a bass exploding on a frog on the surface. They hit frogs HARD, trying to kill them before they eat them (as best I can tell). It's awesome.
I also carry Clousers (chartreuse/white, red/white, blue/white mostly), Beadhead Woolly Buggers (olive, black), seaducers, deceivers, and other streamer flies for the lowly hours during midday when bass are less likely to hit frogs on the surface. But as soon as clouds roll in or the sun gets low and the bass move up shallow again, I tie on a frog. That's fun stuff.
