I haven't fished with the CJS Demon but have used the very similar Lindy Frostee as my go to crappie lure in deeper water for several years. I'm a big fan of the glow colors- red being my favorite, though I've done well with white (moon/silver) and chartreuse as well. Come to think of it, blue has worked too. I prefer the 1/16th oz. size (smallest - 5/8") with each of the trebles tipped with red spikes. Some people swear by Buckshots but I have always had better luck with the Frostee. We get quite a few suspended crappie in the 25-35' depths and the weight of the Frostee allows you to fish fast when the bite is on.
Forage Minnow spoons have also done well for me in similar configurations.
