Nice catch there Jerry. My ears perked up when you said that big one was full of 4" long shad. That should tell everyone that big baits catch big crappie. Match the hatch sort of. Most of last springs shad have grown up or died by now and there may not be many tiny bait fish still around until after it warms up and the next generation hatchs.
Most fo the bigger crappie I have seen coming out of my waters have been caught on big 3" long crank baits. Some of the biggest crappie that I have caught in the past on KY lake were when I was fishing for Bass with Crankbaits. I can remember bringing home some nice crappie that ended up with my stringers of bass.
I never caught them in the numbers though which is why I came to crappie.com to learn where the bigens hang out in numbers. Hopefully I will figure this out on my home lakes and be able to use it on other lakes in the furture.
