I’ve creamed crappies with a naked Swedish pimple in the past but it really depends on the bite. I wouldn’t be afraid to try it but it never hurts to experiment tipping with plastics or other bait. Larger plastics on a jig might be the ticket too so maybe explore a few options to boost your confidence.
I’ve been experimenting with plastics for about 10 years or so and use them 90% of the time for pan fish. I may not catch as many fish some days but they are usually bigger. Crappes in paticular seem to respond well to plastics up to 2″ that have a good tail such as a waxtail or wedge.
I guess the take home message is don’t be afraid of trying something new especially on the days that they are biteing. You may stumble across something that you can use down the line.
