I am fairly new to this site, but in your situation I would do as many people have already recommended. I would use the cranks for the first few passes. After I caught everything I could with the cranks I would go back and fish it with a clean up bait. I would go with a chigger craw on a straight shank hook. I am cheap so the hooks I use are the BPS XPS hooks. I like the 4/0 for the chigger craws. This time of year, I would want something falling a little but slower, so I would go with a 1/4 oz. lead weight. I might even go back with a light jig and a twin tail grub trailer after I fished the chigger craw. I would say with the cranks producing, I would fish them and go to another spot, go back later and fish the texas rigged chigger craw after they have time to settle down.
Good luck in the tournament and hopes this helps.
