When the weather gets really cold, you start experiencing equipment failure and the effects of freezing temperatures. One of the best things you can carry with you on a winter fishing trip is a can of silicone spray. There are all sorts of products made for fishing line, but silicone will get the job done just as well as anything. In icy conditions, especially, you want to spray your line on the spool and your fishing guides fairly often so they don’t ice up as bad. Another thing you want to do is leave your braided line at home in really cold weather. It doesn’t cast very well when it soaks up water and freezes and loses a lot of its sensitivity. I go back to fluorocarbon, or even monofilament. Spraying it with silicone also helps it stay a little more limber so it doesn’t stiffen up so bad in the cold.
