I think this looks like the perfect way to compare rope abrasion resistances; simple and cheap, repeatable, and easily variable with different weights and drum radii and coverings. I think it is better than the Edelrid test I linked above, at least for our purposes:

I guess the result could be explained by the high Denier a monofilament fishing line would have related forum comment. But perhaps its cyclic bend over sheave (CBOS) could be worse than braided?
