That is the first time I have ever seen someone crappie fishing with a baitcaster. I use baitcasters all the time but have never done so when I have crappie fished. I only use spinning gear for that because you are using such a light weight bait, spinning gear makes is much easier to do.
I use 60 lb braid, 1/4 oz jig heads with 3" walleye grubs.
When I get snagged I just rip my jig out of the tree and bend the hook back.
I used to think the same as you until I was invited on a trip several years ago. My buddy told me to leave my spinning rods at home and bring a bass rod with braid. Up until that day that was the most crappie I've ever seen caught in a single trip.
