I have been playing nylon string guitars for 36 years and these are without a doubt the best strings ever and I have tried nearly all of them. These are the loudest, best projecting and best sustaining strings I've ever heard. I've always felt the bass strings on most nylon sets easily overpowered the trebles but not with these. The trebles have an exceptional brilliance and power and yet are not thin or twangy sounding. They still have a very full and rich sound to them with beautiful overtones. They settle in very quickly and the intonation is spot on. I believe these will awaken nearly any nylon string guitar. I use the hard tension full sets. They feel to me like most other hard tension sets.
