It's basically schooling action out the wazoo. Find the shad, and you'll find the fish.
Throw anything that resembles a shad and you'll do well. Keep in mind that most times the fish are all of the same size in a school - so if you're catching dinks out of a school you will contine to catch dinks out of it and need to move on to the next one.
My favorite is getting onto some schooling smallmouth. That's a blast! They'll herd shad like a bunch of cowboys coralling cattle. They'll herd them up on a shallow flat and then explode! Just thinking about that sound is giving me chills right now! Ha ha ha!
If you're fishing a tournament, be sure to have a backup plan just in case something changes and the schools scatter - somedays it's a hot bite and then somedays they just disappear.
