I bought this set for a reproduction of a vintage flamenco guitar.
I might have found the right strings for it, after trying regular nylon and other materials, coating, different tensions, not changing them for months...
The most outstanding feature I feel is with the trebbles, they have a rough-ish surface, this adds a bit extra friction noise almost as if they were wounded like the basses, thus adding sparkle.
I like the feeling on the touch and on the sound, it seems to close the gap between basses and trebbles, very well balanced in all aspects as well as tension, which feels like high, mid-high.
When putting them on I found they where stiffer and stretchier than regular nylon strings.
I only tried real gut strings once and briefly a long time ago but I think this nylgut might have the best from both worlds, synthetic and natural.
I'm loving them.
