X5 Braid Line vs Core G9 Braided Fishing Line Dark Mocha / 15lb / 165yds: which is safer?

Where these two actually differ

• We flag Microplastic shedding from fiber degradation, UV degradation and embrittlement, Mold and bacterial colonization and Surfactant or processing residues in braiding lubricants on the Berkley and not on the Shimano.
• We flag Microplastics release during use on the Shimano and not on the Berkley.
• The Berkley is braided polyethylene fishing line where the Shimano is Braided polyethylene/nylon fishing line, which is most of the difference in these two grades.
• These two are level, close enough that price and fit should decide it rather than our grade.
