Too slippery!
No, these strings are not for me! A lot of people really like them, but I don't!. First of all, the Nanoweb coating makes them feel very slippery under my (left-hand) fingertips. I thought I could maybe get used to this, but after three weeks I've given up. I have several guitars, and the others are fitted with standard, uncoated strings, so I could easily compare them.
Also, they sound too bright and 'metallic' for my taste, but I suppose this is to be expected from 80/20 strings.
Anyway, this is just my opinion.
