Last winter, fishing the Cowlitz on a very cold day, my fishing partner made a cast arond a protruding branch just out of the river. It was one of those casts where you see the line wrap and weave around, kind of in slow motion. It was stuck good so he thumbs down as we drift by. CRACK! the line breaks. He sits down and says that hurt, that really hurt. I wasn't laughing that hard and went to hand him another pole. He says no it hurts. We use #10 black barrel swivels and one of these had gone through a fleece sweatshirt and turtle neck and was stuck into his arm.
