Good morning. I use slip floats and have difficulty keeping the thread set from slipping on the main line after it become wet. You probably know this but let me tell you how I put on the thread in case I am missing something. The thread and bead come on a small plastic tube which slides on the line to the depth you want to set it. Slide the thread off the tube onto the line and pull the two ends tight. Remove the plastic tube. Put bead followed by float on line. Works for a while then the thread begins to slip. As crappie fishermen you know how this change in depth can affect your catch. Any hints, suggestions or tricks to keep this in place are greatly appreciated. Jump'n Jak
