I am new here, so please excuse me if this has already been hashed out. I have seen some talk about these strings elsewhere and I think that there is some confusion regarding these strings. The tension is low, like nylon, but they are not promoted as classical. They are finger style, (fingerpicking), folk strings. I have a 1917 Eugene Howard parlor that wears good, classical strings. I just put a set of the Thomastik PJ116 strings on my Taylor 812ce Deluxe 12 fret, (X braced), and they are very balanced and have surprisingly good sustain and volume. I only play fingerstyle, and the low tension makes barring a pleasure. Surprisingly, the guitar didn’t seem to lose anything. I did have to back the truss rod off, but other than that, it was a seamless changeover. They are pricy compared to most other strings, but for my tired, 64 year old hands, it’s well worth it.
