Think you have a great selection for smallies...I would definetly try some top water...Small walkers and poppers like the Spook Jr., Cultiva Zip n Ziggy, Zell Pop R, LC G Splash work well on spin tackle. But use a mono leader instead of flouro.
I usually toss flies in the trout water but you could try some jigs, cranks, floating & suspending jerkbaits that mimic the forage in the river. Black & Brown stoneflies in the 3/4"-1.25" range, Tan Crawfish in the 1.5-2" range...Olive Craws in the 2-4" range...Dusky Stripe Shiners and Central Rollers in the 3-5" range. Hope you have a great trip.
