Light bites are tough to feel no matter what tackle. Lots of times you can see the bite that would'nt be felt. Hence the use of hi-vis yellow line. First, the fish don't seem to mind the bright color. Crappie feed up due to the position of their eyes on their head. So the result is that they come up and hit the bait while they're still rising. The only indicator is the line going slack. I use a bobber sometimes that looks like a stick with a cork in the middle, and these stand up when at rest. A light bite takes the weight off the bottom and the float lays over. I started catching lots more when I became a line watcher. Hope this helps. Tight lines.
