The Headhunter (my dad fished out of the Headhunter last summer and had a great day, by the way) posted a question about the worst products out there. There were lots of good replies.
There are some goodies on the list. One of my favorites is the line straightener. This is a little do-dad that hangs off your vest and you run it down the leader to straighten it.
It’s a bad idea. Heat weakens tippet. The line straightener is heating your tippet.
