Tiny Torpedos, Zara Puppies, Road Runners with Marabou or 2" & 3" curly tails. 3" Yo-Zuri Pin's Minnows (my all time favorite)
I've been using a 5' and 5.5" UL rod with a Shimano 500 sized reel for more than a decade to catch Smallmouths up to 5.25lbs and Largemouths to 6lbs.
I prefer to use my UL gear when the Smallmouths run out of Lake Champlain up the smaller rivers to spawn. (Lewis Creek, LaPlatte river)
