I don't see any reason they wouldn't work for crappie because a lot of baits that work for Walleye can be used while crappie fishing. Using the stickbait over brush may work very well with a short pause of maybe 1 second, I would think anything longer would let the bait rise back to the top of the water. If you try the stickbait let us know how they work for you. I know I have some and will also give it a try over the summer.
