This is what I know for sure about crapie fishing. When your absolutely positive you've got the pattern all figured out, they'll move shallower or deeper, and if you listen real carful like....you'll hear giggles (they're laughing at us). At that point, cast towards the giggles. With that said, when the water tempertures get above 55, I usually leave the spider rig rod holders at the house and start throwing a jig under a bobber. Remember to always throw towards the giggles.
Just my two cents worth!
Everything is possible. The impossible just takes longer!
