A single spinner trailing a single hook dressed with a small minnow, what we call a panfish leech etc. Plastics would work as will the smallest of the GULP ALIVE minnow baits and leeches. I prefer a metal shaft, which in this case is a short one. The only one I know about is from Lindy/LittleJoe called Little Joe True-Spin Spinner. Google up the name and look at the images. There is nothing complicated about this rig. Plus you can carry it without taking up any kind of space in your tackle box.

I fish these on .006" and .008" diameter copolymer and all it takes to get them down deep enough is a tiny split shot which I normally put up the line a good foot to 16" just ahead of the swivel. This is spinner, so without the swivel you will twist your line badly. I trail a #4 or #6 circle hook, NOT a jig, on the keeper system of the spinner. An octopus hook would work as well. Another variation is to trail a smaller streamer or a hook with just a scant dressing of short bucktail. That is what we used to call a "killer rig". We always added a small minnow to the streamer. I carry both nickel and gold and it is a tossup which I prefer. For me this is a backup technique for when plastics and tiny jigs don't connect. I prefer drifting, casting and vertical jigging, but troll to hunt if nothing else connects.

For that matter you can just as easily troll RoadRunners or BeatleSpins, they will also take crappies on the troll and are much more commonly available. Little Mepps or Panther Martins will also work. IOW the so called trout size.

This is Minnesota so we get one line and one hook per fisherman on open water; so trolling with a couple of other fisherman adds to the effect, but this is not a fast troll; so flash is minimal, just so long as it is there. We want just enough speed to keep the spinners turning. We also fish this pretty shallow; I never weight this with more than 1/32oz. I also troll slower than most people and normally fish smaller waters than a lot of folks so I can target trolling passes pretty closely and still cover the water.
