Aquila 97C Alabastro Classic Set LT

Those are quite good, offering a soft feeling somewhat between Carbon and Nylon, however, on my guitar my favorite is the Perla Strings, even if they don't project as much.

It will depend on your instrument, the strings are quite thick which I appreciate.

I'm a lute player, use Aquila Nylgut on my lutes and am very happy with it. I had to play some 17th century lute music on a guitar and wanted a more lute-like sound, lower tension in particular. I was actually very surprised at how lovely these sounded on a classical guitar - not exactly lute-like, but very expressive, like a 19th century Romantic guitar. Thoroughly recommended if that's the vibe you are after. Tuned up fast and kept tune really well, no issues with string breaks or anything like that. Just superb.

Beautiful sound on cordoba c5

Now this this turned my el cheapo practice Yamaha to an acceptable sounding thing. Amazing strings, I encourage everyone to try these Nylguts, sound clean, crisp, fairly plucky but in a romantic way, easy vibrato. Very expressive, and so much cleaner than basic nylon while has still a warm aura. It's also fairly priced.
