like deathb4disco said, the selection of small poppers sold at WalMart and KMart are good poppers: they catch fish and are inexpensive. Plus catching any kind of fish on the surface, from stripers to bluegills, is a blast. If you tie your own, there's a fly called the Madame X that is killer for Summer sunfish, which imitates a grasshopper. It can also be tied in black to imitate a cricket.
