The Berkley Vanish Fluorocarbon Leader Spools is great for leaders or smaller reels. Nearly invisible and super soft and castable, this line is ideal for those who don't want problems with memory. We find that lines that are more soft tend to not be as strong but Vanish is different. Give it a shot, we think you'll like it's performance.
The only fluorocarbon line that changes color, so you see it, fish don't.
