I first came across these strings quite a while ago, having tried them they are the only strings that I will now use for my two nylon strung guitars, which are a Yamaha AEX500NS, and a LaPatrie 'Motif' parlour. These strings settle down quickly, are very stable and hold their tuning well, and they last, and last! The composite third string achieves a good transition between the wound bass strings, and the nylon trebles. I prefer the extra hard tension, which may not suit everyone, but for me gives the best playing feel. Highly recommended.
