My go to finesse swim bait for small mouths at Monticello are the keitech 3.3 inch fat swing impact small mouth magic color rigged on a owner twistlock light 1/0 or 2/0 hook. No weight needed. I throw it on my bait finesse casting setup (phenix k2 medium light with a shimano scorpion BFS reel). You could throw it on a spinning setup as well. I usually find current seams or little breaks in the current and cast out there, let the keitech drift in the current with occasional rod twitches and reel turns to make the tail paddle. I caught well over 30 smallies today in about 3-4 hours of fishing. You could also use spray scent to help increase bites as well.
