Where these two actually differ
- We flag Microplastic shedding during use on the Ande and not on the Cortland.
- We flag PFAS in waterproof coating (fluoropolymer), Microplastic shedding from coating wear and Mold or bacterial growth if not dried on the Cortland and not on the Ande.
- The Ande is Monofilament nylon fishing line where the Cortland is Fly line with plastic core and waterproof coating, which is most of the difference in these two grades.
- The gap is 45 points, wide enough that this is not a close call, and the Ande is the one to buy.
- We are less certain about the Cortland grade, at 35% confidence against 72%, because it discloses less.
Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
