I have fished the MS River oxbows, barpits and runouts all summer.
If you are in moving water, runout or culvert, it's hard to beat a #2 Rebel Crank. Pearl or any black back. I usually use a red permanent marker to add back the red, pink or orange dot under the lip. I'll draw legs onto the crank with a fine tip black paint pen. I keep it handy. The paint comes off the factory bait after 10 fish .
If that didnt work, I would usually use a baby brush hog. Heavy weight, as I was in moving water most of the time. Hot color this year is/was California 420.
A Rattlin Rogue.....depends on your depth, is a popular summer bait down here. In the morning and evenings, the floater is better. After 8am and before 6pm use the diver with suspension. 4/6 ft, ideally.
Big Cranks, on lake dropoffs and points are money this time a year. Seemed like 3/4 of the river bass I cleaned this year had crayfish in its belly. Sometimes multiple crayfish...and they were still chasing my bait. These bass are different than the Florida Hybrid most people catch. Very aggressive.
