My go to spinner rig is a Cabelas Super Glow in the Dark floating 2 floats, 2 hook worm harness or single hook with a Gulp leech. In stained waters like Kawnipi these glow in the dark harnesses do real well. I like  blue, chartreuse and pink.

I adjust snell length depending how far walleye are off the bottom. Most prepackaged glow rigs come with a 48 inch snell ...I normally shorten it up to about 30 inches on average when trolling 2 mph.

I use a quick change Lindy swivel ahead of the spinner rig to reduce line twist.

I just don't think Gulp worms /leeches give you the great action of a live worm or leech. Maybe what Jaximus is suggesting ( slow death set-up) might give more action than my artificial setup.  I think more action  is needed many times when fish are neutral or negative.
