Where these two actually differ
- We flag Coating composition unknown (non-PFAS additives), Dermal irritation from additives and Degradation and leaching over storage on the Spiderwire and not on the Ande.
- Both carry a flag for Microplastic shedding during use, so neither choice avoids it.
- The Ande is Monofilament nylon fishing line where the Spiderwire is Braided polyethylene / nylon with unspecified coating or finish, which is most of the difference in these two grades.
- The gap is 35 points, wide enough that this is not a close call, and the Ande is the one to buy.
- We are less certain about the Spiderwire grade, at 45% 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 →
