Slip vs fixed float for winter bite

[glasseyes]

Try using an unweighted float and add some bigger split shot above your jig. (This is called a "bulk plus dropper" pattern.)

The bigger shot will pull the line through better, and you will still get the slower drop from the light jig.

Yes I've tried that in the past and doesn't work so well when crappie bite is lite and also on the bite coming from under some times you don't see it at all.
To remedy this I use the rocket bobber , it works only with 1/64th and 1/32 nd weighted jigs but works like a charm, can cast it a mile and the slightest hit on jig pops the bobber up.
