Monofilament vs Ultracast Braid: which is safer?
Ande Monofilament is the clear pick. Spiderwire Ultracast Braid carries a failing PFAS grade, and we never recommend buying a failing product.

Where these two actually differ
- We flag Microplastic shedding during use on the Ande and not on the Spiderwire.
- We flag Microplastic shedding from braided structure, Undisclosed coating additives with potential leaching, UV degradation and polymer fragmentation and Dermal or ingestion risk from handled coating residue on the Spiderwire and not on the Ande.
- The Ande is Monofilament nylon fishing line where the Spiderwire is Braided polyethylene fishing line with undisclosed coating, 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 35% confidence against 72%, because it discloses less.
Both products run through the same public rubric, which covers 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 →
