I fish these and most of the plastics under a float until the spawn gets started. In the spring I find crappies very depth oriented and that means keeping the bait at a specific depth. I use a #2 Thill Mini Stealth float [shaped like an acorn with a short stem with a hole in the end below the balsa] when using the 1/32 heads. Larger heads I cast/retrieve. This particular float is the master of showing upward hits. To keep them horizontal in the water I adjust the knot on the eye of the jig towards the hook's point slightly and add a mere speck of super glue to hold it. Some days the fish really need to see it straight horizontal while other days they don't appear to care less.

I let the fish tell me what and how they want things. For the most part though, from the time I can find open water between sheets of ice right up until I quit fishing crappies during the spawn I use a float almost exclusively. From that point until we see cold water again in the fall I will use a float only when circustances demand it. Late fall will see the float back.
