X5 Braid Line vs Countdown Elite: 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 Rapala.
• We flag Paint or enamel coating degradation and microplastic shedding, Metal corrosion and nickel leaching and Plastic body brittleness and breakage on the Rapala and not on the Berkley.
• The Berkley is braided polyethylene fishing line where the Rapala is Plastic body, metal hooks and split rings, 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.
