To straighten heavy monofilament for tarpon leaders, cut a 25 inch piece of 1/4 inch PVC pipe and install a cap on both ends. Cut the mono to length and put as many pieces as you can in the tube. Over the sink, pour boiling hot water into the tube with a cap on one end. The mono will straighten immediately. Allow to cool and cap the other end.
Ease your work load and use Seaguar 60 pound Fluorocarbon. This material is easily stretched on the boat and has a greater abrasion resistance.
