First, welcome from Debary, another neighbor to Slimjim that fishes Lake Monroe. Twister tails, beetle spins, roadrunners, and tail spinners all work fine. Sometimes. You already know how finicky they can be and some days they want flash and others they don’t. A lot of us run lots of rods and put different baits and colors out til the fish tell us what’s gonna work that day. I’ve trolled the river some too and par for the course, sometimes it’s great and others not a fish. Already said is to fish before the heat this time of year. I have some days when they seemingly throw a fish and stop eating around 9 or 10 o’clock. Hope this helps and good luck when you go.
