Love fishing spinnerbaits for river smallmouth, I run them all summer after the top water bite slows around 8 am. My favorite is the strike king mini king. We really had smallmouth killing them when we used gulp swimming minnows and gulp twister tails as trailers.

Used them in creeks a lot for smallies. Not one particular brand worked better than others but I always carried a variety of colors and a mess of twister tails to match up a trailer. Same setup for largemouth in lakes too
