I play a variety of instruments but mainly brass and guitar. The styles are jazz or close to jazz, including flamenco guitar. Because I wanted a nylon string guitar I could play in an amplified setting, I bought an Ibanez EWN30SYE-NT which (when properly set up) is excellent amplified and not too prone to feedback.
Because I use flatwounds on my archtop guitar and fretless bass, I decided to try flatwound classical nylon strings.
I was VERY HAPPY with the result. They are described on the Thomastik website as a "student or practice string": I would consider them of professional standard in non-classical fields. For jazz guitarists using nylon string guitars they are excellent. They produce a nice variety of tones without adjusting the guitar's EQ.
Needless to say, the string noise when moving around the neck is much reduced (not eliminated). They are much more comfortable under the pads of the fretting fingers and less abrasive to fingernails.
Because this set has a this, wound G string, rather than unwound nylon, it may allow steel string players venturing into nylon to feel more comfortable. I would even recommend classical guitarists to try them: you may be surprised...
