Any fluorocarbon leader BELOW .350mm in diameter can be safely used with our 23lb Floating Mono mainline without excessively stretching the mainline in order to break free leader snags.

Remember, every time a setup is pulled to break a leader on a snag, the mainline is stretched and weakened.   All monofilament lines when excessively stretched are weakened.   At some point, that section of mainline must be cut back and re-tied to maintain maximum breaking strength.   No monofilament can withstand endless occurrences of stretching/elongation and not eventually fail.

If a particular leader is NOT listed below, then it's actual diameter is in excess of .35mm and it can NOT be used under our 23lb mainline because it's diameter is far in excess of its labeled breaking strength.

If your choice of leader‘s diameter is in excess of what is listed below, you should move up to our 28lb Floating Mono mainline.
