Replaced the Savarez strings on my Cordoba and Sigma (yes, a classical Sigma) guitars. Found these to be more comfortable on the fingers, slightly brighter in sound. One of the pleasant surprises was the easy playability; just the slightest touch brings forth a rich, pleasant sound. I cannot speak to the projection, as I only play for myself, but the ease and clarity of the sound was pure pleasure. For those who worry about such things, the strings tied easily and stayed in place without undue effort.
