I decided to experiment with these strings and I was not disappointed. Contrary to the common misconception, these strings do not make your instrument louder, but they do have a nice effect on the harmonics behind individual notes. Natural harmonics sound really nice with these. They also seem to hold that new string sound a little longer but I might be wrong on that.
On the flip side, these definitely feel rougher on my fingers, but I got used to that pretty quickly.
