Having been a round wound user (Rotosound & Elites mainly) for about 20 yesrs, I recently switched to LaBella Flatwounds. I am converted. They are not as bright as round wounds, the brightness I never really liked so I tended to change my strings less often than most. I also find that I can play licks using flatwounds much quicker and slicker than before, and with no left hand shifting string noise.
