Now, if by break you mean fraying by rubbing up against some rocks or pilings, the Fireline, a fused braid, will last a little longer than Suffix the pure braid, but neither will last as long as Flouro or Mono.

All things being equal in terms of the diameter of the line, you can spool an equal amount of 50lb-test Suffix, 30lb-test Fireline, 15lb-test flouro or 10lb-test mono. (Give or take, depending on the brand of mono and flouro, some are stronger than others).

Your analysis is purely theoretical and rests on the assumption that both line breaking strength, and their diameters, are accurately represented by the manufacturer.

Based on my experience with these lines, that is an unfounded assumption
