Mike, aside from spawning season, my best luck with RES is on firm soil (or small rocks) using tiny crawfish as bait. I'm talking craws under an inch, if possible. I used to catch bait in drainage ditches and use them on False River, Louisiana. Sometimes bass or BG would whack the craws, but the RES seemed to particularly love 'em.
Of course, if you have grass shrimp, everything will hit it, including RES. But if you want to target RES, hard to beat little craws!
