I went out on a curious limb buying these strings having no idea how they would play. All I can say is... wow. The sheer amount of volume, the clarity of the sound, the feel under the left hand and the response under the right hand, all fantastic. They have set very quickly, hold their intonation very well, and frankly they even look great! I've only put them on so I can't attest to their longevity, however for new strings they're relatively squeakless. I imagine I will be buying them again.
