Sometime's I envy you guy's in area's where there's lot's of crappie to fish for. Wish we had them around here. Also wish we had all the tackle you guy's have. Guy that first took me for crappie, year ago, used a bobber but not a slip bobber. I wanted to use slip bobber's and about all I could find were pretty heavy plastic bobber's for salmon fishing. Finely found some small cork one's, maybe 3/4" through. Really light and can be hard to see depending on glare on the water. But love it when the little thing disappears! I tried using the bobber stop quite a bit deeper and found it snagged on the tip of the rod and moved the slip knot around. I make them from some thread I found in my mother's old sewing cabnit that seem's to be the same size as the commercial one's. Commercials one's, that's a joke. Didn't know how to tie them so bought a lot of commercial one's and then learned to tie them. Now I've got all these commercial one's and am mostly using my owm. Flaw in that though. The commercial ones are tied with some kind of high visibility green thread and I can watch the jig go down by watching the bobber stop. I can also tell if the jig is down as the bobber stop then sit's on top of the bobber and I can see it.
