I've been catching a lot of bass lately using crappie spins and realized I never hear much about them.

Anybody else use crappie spins for bass?

I do. I have a couple in my 'panic box'. They also work well early and late in the year when the water is cold and clear.

My wife fishes them all the time because she only uses spinning rods and they fish much easier than a regular bass sized spinnerbait. Bass really seem to like them a lot at times.
