Scrounger jigheads are awesome for so many species of fish and they work great for rainbow trout too. You can rig a variety of baits on a scrounger jighead, but for rainbow trout, you’re going to be using 2 main finesse baits. These will be finesse worms and minnow-style baits. Cast them out and retrieve them slowly. The action can be flat out awesome and rainbow trout will eat them up.
