Use marker floats that come with the Rapala scale. The cheap clips will come off fairly easy. I replace the clips with big safety pins that come from Michael's or Hobby Lobby in the craft area. The floats the bass guys use are also OK but are a little over kill for crappie. The colored rubber tubes are OK also but replace the clips. And with the tubes, you need something to write on to keep up with the weights of each color. I saw a new system from Ardent where the floats have dials and you can enter the weight on the floats with 2 dials. BassPro and Cabelas has them. Ardent Smallcull system.
