A lot of good info coming in here! I found this video, and I was surprised by the results as well! I'm not trying to change anyone's mind - use what you have CONFIDENCE in! I use 20# Trilene XT Low Vis Green for my leaders... Does it get nicks and frays? Yes. But I can tell you honestly, the biggest fish i ever lost behind the boat pulled a wire harness apart with breaking the leader....guess that one didn't have any nicks! lol

Check out this video....interesting test of mono vs. fluoro abrasion resistance....
